| The Taihang Mountain is both the ecological barrier of the North China Plain and a highly overlapping area of national poverty zones and ecologically fragile areas,and now is in a period of rapid urbanization and industrial development.Due to the constraints of the natural background and the influence of development methods,the advantages of land resources in the Taihang Mountain of Hebei Province have not been fully manifested.According to the founder of classical economics,William Petty,labour is the father of wealth and land is the mother of wealth.As the carrier of people’s production,life and ecology,land is especially the material basis for the construction of ecological civilization.The interrelationship between land resources development and socioeconomic development is centrally expressed in the allocation of land resources to various industrial land sectors,and the effectiveness of land use is measured by the amount of products and services exported by the land sectors,and industrial development and land use are mutually constraining and interactive.General Secretary Xi Jinping stressed that "we should thoroughly implement the concept of green water and green hills is the silver mountain of gold,organically combine ecological governance and the development of special industries,and walk out a road of coordinated ecological and economic development and harmonious coexistence of man and nature." Under this new situation,how to give full play to the ecological advantages of the Taihang Mountain to enhance its land use efficiency has become the core issue of regional development and rural revitalization.In this context,exploring and establishing the theory and evaluation methods of land use efficiency in mountainous areas has become an important issue for the sustainable development of the Taihang mountainous area in Hebei.This paper is based on the research idea of "theory introduction-practical application-theory enhancement".Based on the actual demand for the effective connection of targeted poverty alleviation and rural vitalization strategy in the Taihang Mountain Area of Hebei Province,this article gives in-depth analysis of the status of land use benefits in this area.From the perspective of comprehensive,economic,social and ecological benefits from land use and with relevant theories and methods of Land Use,Land Economics,Geography,Statistics and other disciplines,it aims to establish an index system of land use benefit evaluation from a county-area perspective in the Taihang Mountain area of Hebei Province.This article has applied Python and "3S”technology,by integrating remote sensing images,statistical data,survey data and other multi-source data,and comprehensively used entropy weight analysis,TOPSIS analysis,obstacle degree model,ARCGIS spatial analysis,FLUS prediction model and other methods,in order to systematically analyze and evaluate the comprehensive,economic,social and ecological benefits of land use in the typical years of 2011,2015,and 2019 and identify the obstacles that hinder the utilization of land use benefits in the Taihang Mountain Area of Hebei Province.This article has also combined DEM data on the above research to simulate the land space development pattern of the Taihang Mountain Area of Hebei Province under different land use benefit scenarios,so as to fully realize the regional land space planning and rural vitalization.This can also provide typical cases,countermeasures and suggestions for the construction of a land use benefit improvement mechanism in the Taihang Mountain Area of Hebei Province.This article finds that:(1)There is great variation in terms of the comprehensive,economic,social,and ecological benefits of land use in the whole area and different counties of the Taihang Mountain Area of Hebei Province.①From the perspective of the comprehensive benefits of land use,the hilly area in the southern Hebei Province has a higher benefit than the mountainous areas in the north.The land use benefit of Wu’an,in southern Hebei’s Handan City,is the most prominent,with a high land use benefit;Fuping County,Shunping County and Laiyuan County of northern Hebei’s Baoding City have the lowest land use benefit.②From the perspective of the economic benefits of land use,the economic development level of the northern mountainous area is lower than that of the southern mountainous area,with Wu’an City,Luquan District and Yongnian County rank highly in land use benefits,Shunping County,Fuping County,Quyang County,Jingxing Mining Area and Lincheng County are low in land use benefits.③From the perspective of the social benefits of land use,the level is generally low.Most counties and cities are at a low level of land use benefits.Only Wu’an City has a high-quality level but no other counties has reached a good level.Zanhuang County,Fuping County and Laiyuan County are at the bottom level.Even though Fuping County ranks low in the land use efficiency,it has increased by 239.17%compared to 2015,which is a notably fast rate.④From the perspective of the ecological benefits of land use,there is still huge room for the northern mountainous areas to improve.The counties with high-quality are Yongnian County and Yuanshi County,and the last three counties are Shexian County,Yuxian County and Laiyuan County.Different from economic benefits and social benefits,the ecological benefits of land use in different counties vary greatly from the rankings of social and economic benefits.(2)The ranking of obstacle factors and obstacle factors for land use benefit in the Taihang Mountain Area of Hebei Province shows that the obstacle degree of social benefit of overall land use in the study area are relatively large.With the country’s increasing investment in poverty alleviation in mountainous rural areas,the obstacle factors for land use benefit is changing from economic obstacles to social obstacles.①From the perspective of the overall land use benefit obstacle degree in the study area,the social obstacle degree is the highest,indicating that the social benefits of land use in the Taihang Mountain Area of Hebei Province lag behind economic and ecological benefits.From the perspective of obstacle factors,among the top 8 obstacle factors in the 3 typical years,social benefit factors account for 5 or 6,among which Engel’s coefficient,the number of villages passing tap water and urbanization rate are particularly prominent.②From the perspective of the obstacle degree of land use benefits in each county,no matter high,medium or low level of land use benefits,the obstacle degrees of per capita road area,urbanization level and per capita arable land area are particularly prominent in the social benefits.The analysis of obstacle degree and obstacle factors of land use benefits reflects that since 2011,the Taihang Mountain Area of Hebei Province has been continuously improving its ecological and economic benefits in the targeted poverty alleviation fight,and the full play of social benefits has become the focus of rural revitalization after 2018.(3)Based on the results of land use benefits evaluation,obstacle degree and obstacle factors in the Taihang Mountain Area of Hebei Province,the FLUS model is applied to simulate the natural growth scenario,urbanization development scenario,economic priority scenario and ecological priority scenario pattern in 2025.The simulation forecast results show that:①The social benefits of land use in the Taihang Mountain Area of Hebei Province have much room for improvement.Under the urbanization development scenario,the prospects for rural and ecological land use are good,which will promote the balanced development of land use benefits.②The red line of ecological benefits of land use in the study area needs to be highly valued.As the ecological barrier and water conservation area for Beijing-Tianjin-Hebei area,except for the priority scenarios of ecological benefits and cities and towns,the ecological land use in other scenario simulations have been reduced,which should be given high attention in planning.③The agricultural production and lifestyle in the Taihang Mountain Area of Hebei Province need to be improved.The results of multi-scenario prediction show that the number of rural residential areas will only decrease or remain unchanged in the future,but not increase.Especially in the context of urbanization development,the intensive and economical use of land in rural residential area should be focused on.Meanwhile,the change of the arable land area should also draw enough attention.Besides guarding the red line of arable land area,increasing the output value of agricultural land and the economic benefits of land use will become the focus of agricultural and rural development in the Taihang Mountain Area of Hebei Province.It is also the key to the full implementation of the rural vitalization strategy at the earliest in this area.The innovation of this paper is to construct a comprehensive evaluation index system for the effectiveness of land use in mountainous areas,highlighting the economic,social and ecological benefit features of land use in mountainous areas and evaluating the effectiveness of land use in the Taihang mountainous area of Hebei Province in a more comprehensive manner;based on the diagnosed barrier degree and barrier factors for the effectiveness of land use in the Taihang mountainous area of Hebei Province,combined with the national policies on the Taihang mountainous area of Hebei Province during the construction of poverty alleviation and development,precise poverty alleviation and rural revitalisation This study is a multi-situational simulation of future land use in mountainous counties to provide countermeasures and suggestions for rational land planning and comprehensive benefits in mountainous areas. |
