Analysis And Scenario Simulation On The Land Reclamation Of Wang Jia Jceramic Earth Mine In Renhua County

This paper is based on the kernel county,the wangs ceramic soil mining area of the status quo of land damage degree evaluation and put forward the suitable for this area land reclamation measures,in addition,the-Markov model to natural landspe pattern mining area land reclamation development,economic development,ecologil security and planning guide the development of four different scenarios simulation studies,It is of great signifince to study the regional ecologil security protection and the coordinated utilization of resources.According to this paper,the main results are as follows:(1)The open-pit stope in Wangjiatao porcelainite coal mine area of Renhua County has the greatest impact on the land damage,which belongs to the severe damage,accounting for85.1% of the total area to be damaged.Other subareas,such as dump,living area,industrial site and road in mining area,have less damage to the land in mining area,accounting for14.9%,and most of them are in the form of occupying the damaged land.(2)Mining activities will affect the soil,biology,water resources,geologil environment and so on in the Wangjia ceramic soil coal mine area of Renhua County,among which the impact on land resources is the greatest,followed by the impact on geologil landspe and geologil disasters,and the serious areas mainly include stope,dump,office and living areas and mine roads.(3)According to the simulation results of four scenario models of natural development,economic development,ecologil security and plann-guided development,there are great differences in the spatial distribution of future land use change in Wangjia Ceramic Coal Mine Area of Renhua County.Construction land is mainly distributed on provincial roads,but the shape of construction land is different under different scenario models.In the se of ecologil protection,the construction zone is the longest,while in the se of economic development,the construction zone is the widest.In the se of planning guidance,most of the construction land is relatively neatly distributed in the economic development zones.(4)Due to the different main goals set by the four different scenario models,the quantity conversion of each land use type in the future of Wangjia ceramic clay coal mine area in Renhua County is also quite different.Under the natural development scenario,the construction land increased,and the forestland decreased.In the economic development scenario,construction land increased,and cultivated land was the main source of expansion of construction land.In the ecologil security scenario,the area of garden,water,cultivated land and woodland all increased,while the expansion of construction land was restricted.The area of cultivated land increased the most.Under the guidance of planning,the construction land expanded to a certain extent,but the growth rate was relatively slow.The area of other land types in the land reclamation of mining areas decreased the most.Therefore,the increase of construction land was mainly from the new development and construction of the original undeveloped land,rather than from the occupation of cultivated land.(5)In the future,the conversion of cultivated land into construction land should be reasonably controlled,and the quantity and quality of cultivated land should be effectively increased.Beuse the simulation results of landspe evolution and distribution of land reclamation in Renhua Wangjia clay mining area under different scenarios show that land reclamation and regional development may be at the cost of arable land resources.
