摘要:

为了解“十二五”期间全国坡耕地水土流失综合治理工程实施情况,在资料收集、典型调研和专家咨询的基础上,从工程管理、工程建设、实施效益三个方面共选取24个指标,运用层次分析-灰色关联分析法对各省区工程实施效果进行综合分析评价。结果表明:(1) 大部分省区工程建设得分>0.65,得分较高,工程管理和实施效益得分多在0.45-0.65之间,总体得分偏低;(2) 综合评价结果呈正态分布,四川省、云南省、贵州省综合得分分别为0.71,0.68和0.67,实施效果良好;吉林省、辽宁省得分分别为0.38和0.42,实施效果有待提升;其余各省得分均在0.45-0.65之间,效果中等;(3) 评价结果在空间上呈现一定的地带性规律,西南岩溶区实施效果最好,其次是西南紫色土区、西北黄土高原区、北方土石山区和南方红壤丘陵区,东北黑土区实施效果有待提升。

Abstract:

To understand implementation of a nationwide sloping farmland soil erosion comprehensive control project during China’s 12th Five-Year Plan we used data collection and expert consultation. We selected 24 indexes across three aspects including project management, engineering construction and implementation benefit and used AHP-grey correlation analysis methods. We found that the scores for engineering construction were greater than 0.65 in most of the provinces, autonomous regions and municipalities. These scores are high and scores for project management and implementation benefit are between 0.45-0.65; however, overall scores are low. The comprehensive evaluation results are normally distributed. The composite scores for Sichuan, Yunnan and Guizhou are 0.71, 0.68 and 0.68 respectively, indicating that the implementation effects are good. The scores for Jilin and Liaoning are 0.38 and 0.42 respectively, indicating that the implementation effects need improvement. Scores for other provinces are between 0.45-0.65 and the effects are medium. The evaluation results show certain zonal rules spatially and the implementation effect in karst regions of Southwest China is the highest, followed by the purple soil region in Southwest China, Loess Plateau region of Northwest China, earth-rock mountain region of North China and red soil hilly region of South China. The implementation effect in the black soil region of Northeast China suggests that improvement is needed in this region.
