【摘要】：本文以山西省采煤土地损毁为研究对象,基于不同类型的土地损毁系数计算得出山西省2000~2010年间煤炭开采平均土地损毁系数为0.2509hm2/万t煤。采用散点拟合法和多元回归分析法,立足不同尺度探讨了损毁土地面积与影响因素之间关系。研究表明:在山西省尺度,煤炭基础储量、耕地面积是影响土地损毁面积的负相关性因素,而地区生产总值、煤炭工业投资是影响土地损毁面积的正相关性因素。在煤炭基地尺度,体现出地区生产总值对土地损毁面积的正相关性,耕地面积对土地损毁面积的负相关性。在煤炭产地尺度,基本上能体现出地区生产总值对土地损毁面积的正相关性,但耕地面积对土地损毁面积的负相关性体现不明显。此外,山西省尺度和煤炭基地尺度是利用地区生产总值和耕地面积控制采煤土地损毁面积的最佳尺度。
[Abstract]:Based on the calculation of the land damage coefficient of different types of coal mining in Shanxi Province, the average land damage coefficient of coal mining in Shanxi Province from 2000 to 2010 is 0.2509hm2/ ten thousand tons of coal. By using scattered point fitting and multiple regression analysis, the relationship between damaged land area and influencing factors was discussed based on different scales. The results show that in Shanxi Province, coal reserves and cultivated land area are the negative correlation factors, while the regional GDP and coal industry investment are the positive correlation factors. On the scale of coal base, the positive correlation of regional gross domestic product to land damage area and the negative correlation of cultivated land area to land damage area are reflected. In the scale of coal producing area, the positive correlation between the gross domestic product and the area of land damage is basically reflected, but the negative correlation between the area of cultivated land and the area of land damage is not obvious. In addition, the scale of Shanxi Province and the scale of coal base are the best criteria for controlling the damaged area of coal mining land by using regional gross domestic product and cultivated land area.
