煤炭资源的大规模开采,造成耕地资源大面积损毁,严重威胁我国的粮食安全,制约了矿区可持续发展。目前开采沉陷对耕地的损毁研究主要集中在经济层面,忽视了耕地资源所具有的生态服务功能以及社会保障功能。文中根据资源价值理论,结合郑州矿区实际情况,定量评价了煤炭开采所造成的不同损毁程度的耕地资源价值损失,其中,轻度损毁的耕地价值损失2639元/hm2/a,中度损毁的耕地价值损失7737元/hm2/a,重度损毁的耕地价值损失22715元/hm2/a。该方法能够较为全面地反映开采沉陷对耕地资源的损毁情况,为合理制定矿区耕地资源补偿方案提供依据,具有较好的应用前景。
Large-scale mining of coal resources, resulting in extensive damage to arable land resources, a serious threat to our food security, restricted the sustainable development of mining areas. At present, the studies on the damage of cultivated land by mining subsidence mainly focus on the economic aspect, neglecting the ecological service function and social security function of cultivated land resources. According to the theory of resource value and the actual situation in Zhengzhou mining area, the paper quantitatively evaluates the loss of cultivated land value due to different degrees of damage caused by coal mining, in which 2639 yuan / hm2 / a of mildly damaged cultivated land, The loss of value is 7,737 yuan / hm2 / a, and the loss of severely damaged cultivated land is 22,715 yuan / hm2 / a. This method can reflect the damage of arable land resources in a more comprehensive way and provide the basis for the reasonable formulation of arable land resource compensation plan in the mining area, which has a good application prospect.
