Comprehensive Benefits Evaluation of Land Use in the Shuonan Mining Area Based on Triangle Model

摘要

As a carrier of all things, land resources are very limited, the contradiction between human and land has become one of the focus of human survival and development. In the coal mining area, the land occupation and subsidence caused by the exploitation of coal resources continue to aggravate the contradiction between the economic benefit, social benefit and ecological benefit of land use, which directly affects the sustainability of land use. Based on the full utilization of the land resources in the mining area and improvement of land use benefit in the coal mining area, the economic, social and ecological benefits of land use in the coal mining area were analyzed comprehensively, and the comprehensive benefits evaluation index system of land use in coal mining area was built, then the weights of the evaluation indexes were determined by entropy method. According to the quantitative analysis of land use benefit in coal mining area, the triangle model was used to evaluate the comprehensive benefits of land use in mining area from 2005 to 2014. Through division of land use benefit types in coal mining area, the three trends of benefit are analyzed, and the inherent factors of land use efficiency fluctuation in coal mining area are revealed, which provides the basis for strengthening the sustainable land use in coal mining area.
