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0．2509hm^2/万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。
In this paper the average land damage coefficient was calculated according to the land damage coefficient based on landform types and land damage coefficient based on damaging types .During 2000-2010 , the average land damage coefficient for the production of per ten thousand tons of coal was with an average value of 0 .2509hm^2 .The four factors that impose significant influences on coal mining scales were selected in this study to investigate their correlations to the land damage areas from different scales .Particularly , both multivariate and single variable regression equations were obtained .At the Shanxi province scale ,the land damage area negatively correlated to the basic coal reserve and the arable land area ,while positively correlated to the coal industry investment and the gross regional product .Similarly ,at the coal production base scale ,the land damage area in all three coal production bases were positively correlated to the gross regional product while negatively correlated to the arable land area .In contrast ,at the coal production county scale ,a positive correlation between the land damage area and the gross regional product was significant , whereas a negative correlation between the land damage area and arable land area can not be identified . Meanwhile ,Shanxi province scale and coal base scale were the optimal scales on controlling land damage area based on gross regional product and arable land area .
