采用统计分析和情景模拟法,将黄土丘陵区损毁耕地程度划分为:轻度、中度和重度。在三种沉陷后地形坡度下进行单体工程设计,得到损毁耕地在不同情景下复垦静态亩均费用:<5°耕地区,轻度损毁4082元,中度损毁5 455～5 610元,重度损毁11 374～12 283元;5～15°耕地区,轻度损毁6 635～7 389元,中度损毁7 509～8 262元,重度损毁10 996～11 751元;15～25°耕地区,轻度损毁8 386～9 442元,中度损毁9 259～10 318元,重度损毁12 748～13 804元。费用高低与损毁程度、地形坡度、土方运输距离相关。以中煤平朔潘家窑矿为例,采用MSAS、GIS手段实证分析,结果表明:潘家窑矿耕地以轻度、中度损毁为主,平均静态亩均费用7 016元,且费用构成中土地平整工程所占比重最大。
Using statistical analysis and scenario simulation, the degrees of arable land loss in the loess hilly region were classified as mild, moderate and severe. In the three subsidence terrain gradient monomer engineering design, the damaged cultivated land was damaged in different scenarios reclamation mu average cost: <5 ° cultivated area, slightly damaged 4082 yuan, moderately damaged 5 455 ~ 5 610 yuan, The severe damage was 11374-12303 yuan. In the area of 5-15 ° cultivated land, the slight damage was 6 635-7 795 yuan, the moderate damage was 7 509-822 yuan and the severe damage was 10 996-11 11 75 yuan. The 15-25 ° cultivated land Area, slightly damaged 8386 ~ 9442 yuan, moderately damaged 9259 ~ 10 318 yuan, heavy damage 12 748 ~ 13 804 yuan. The level of damage is related to the degree of damage, topographic gradient, and earthwork transport distance. Taking Pingshuo Panjiayao coal mine in China Coal as an example, the empirical analysis by means of MSAS and GIS shows that the average cost per mu is 7 016 Yuan per mu Land leveling project accounted for the largest proportion.
