| The project of returning farmland to forest is an important forestry ecological construction project in China.It plays an important role in restoring and reconstructing forest vegetation,improving ecological environment,and improving the stability of regional economic and social development.In order to understand the effect of the project of returning farmland to forest in Qiaojia county of Yunnan Province since 2002.In this paper,based on the full use of relevant literature,using the way of field research,the basic information of the county and the relevant data and situation in the implementation process of the project of returning farmland to forest were collected,and the economic,ecological and social benefits of the project were comprehensively analyzed by using statistical knowledge and comparative analysis method Shengqiaojia County Grain for green project quality related measures,in order to provide reference for the future construction of the project.The following conclusions are drawn here(1)Qiaojia county has diversified land types..The total land area of Qiaojia county is 319400hm~2,including 74878.88hm~2of cultivated land,accounting for23.42%of the total land area.However,the proportion of slope farmland is relatively large.The land of 15-25 degrees is about 23951.1 hm~2,accounting for31.99%of the total cultivated land area,and more than 25 degrees of cultivated land is not a small number,including 178500.9hm~2of forestry land,accounting for 55.9%of the total area;72580.8hm~2of forest land,accounting for 22.7%of the total land area;14.9hm~2of sparse forest land;80609.0hm~2of shrub land area,accounting for 25.2%of the total land area There is still a lot of room.(2)The project of returning farmland to forest continued to advance in Qiaojia county.Since 2002,Qiaojia county responded to the national policy of returning farmland to forest.Since then,it has completed 13400 hm~2of farmland to forest,11133.3 hm~2of barren mountain afforestation,consolidated the achievements of returning farmland to forest,and created 11120 hm~2characteristic economic forest.Since the conversion of farmland to forest,the area of high-quality cultivated land in Qiaojia county has been increasing,and the utilization of land resources has been rationalized and diversified.The project of returning farmland to forest has achieved high-efficiency growth in2014-2019,reaching its peak in 2018,with an average increase of 4.2percentage points compared with the previous years.(3)The project of returning farmland to forest in Qiaojia county has achieved remarkable benefits.During the period of returning farmland to forest from 2012 to 2018 in Qiaojia county,the total grain output also increased significantly.The grain output per mu increased from 250 kg to 400 kg;the total grain output increased by 20%;in 2019,the walnut planting area in the county had reached 55666.6 Hm~2,with the output value of more than 500 million yuan;the planting of Zanthoxylum bungeanum was 20466.6 Hm~2,realizing the output value of nearly 550 million yuan;the planting of mango and sericulture was84533.3 Hm~2,realizing the output value of nearly 960 million yuan;the planting of chestnut was 566.6 Hm~2,realizing the output value of more than 40 million yuan The industry has reached nearly 2.1 billion yuan.In terms of ecological construction,the cultivation scale of trees,shrubs and trees and shrubs in Qiaojia county from 2015 to 2019 is relatively large.In2015,the total cultivation amount of three types of trees was 1133.3 Hm~2,666.7hm2 in 2016,2000 hm~2in 17 years,10000 hm~2in 18 years,and 8579 hm~2in 19years.Compared with the biomass and litter amount of different afforestation sites in 2015 and 2019,the total biomass of different afforestation sites in 2019was 149.9t/hm~2,increased by 6.5t/hm~2compared with 143.4t/hm~2in 2015;the total amount of litter in different afforestation sites in 2019 was 145.7t/hm~2,increased by 40.7t/hm~2compared with 105T/hm~2in 2015.It has played an active role in soil and water conservation,prevention of natural disasters,regulation of local climate and protection of wildlife.In terms of social benefits,the energy utilization structure has been optimized.By 2018,a total of 42104 biogas digesters,75700 eye firewood saving stoves and 37804m~2solar energy have been built in Qiaojia county.The public’s awareness of ecological and environmental protection has been enhanced,their enthusiasm for participating in the conversion of farmland to forests and their enthusiasm for consciously protecting the achievements of returning farmland to forests have been improved.(4)The problem of returning farmland to forest still exists in Qiaojia county.Qiaojia county has made some achievements in the project of returning farmland to forest,but there are some problems,such as inadequate implementation of policies,inadequate publicity,insufficient guarantee for project implementation,and low coordination between ecological protection and economic development.In the next step,we should further consolidate the achievements of returning farmland to forest,further improve and implement the policy of returning farmland to forest,improve the quality of the project,strengthen the publicity and education of the project,strengthen the industrial structure adjustment of Qiaojia county,enhance the regional economic strength,strengthen the talent construction of the implementation of the project,and strengthen the management of the project Construction of supervision and evaluation system for the project of returning farmland to forest. |
