摘要
基于高标准基本农田建设工作的开展,以盐亭县为例,从建设后的自然质量、建设任务完成情况和综合成效3个方面进行分析,选取土层厚度、土地平整工程量、提高粮食生产能力等14个因子,用熵权法测算各评价单元的建设成效性,将其建设成效评价划分为4个等级。结果表明:在高标准基本农田建设中,成效评价为优良的项目占总项目数的61.90%,占建设总面积的63.39%;只有2个项目所占的4.76%的建设总面积评价结果为差。该研究结果可为后期建设高标准基本农田提供科学依据。
The High-Standard Prime Farmland Construction （HSPFC） plays an important role in improving gross national product and promoting agricultural modernization. This program took the Yanting County as an example to assess the effective evaluation of HSPFC. Based on analysis of three aspects on natural quality after HSPFC ,completion status of HSPFC ,and comprehensive effect of HSPFC ,firstly we selected total 17 factors （such as soil depth, quantity of land leveling, ability to improve food production et al;then calculated effectiveness of construction in each evalua- ted element by combining entropy weight method with approximation method of perfect solution ;finally classified the effective evaluation of HSPFC into four levels. The results indicated that the percentage of HSPFC programs whose effective evaluation were excellent occupied 61.90% of total programs, and the areas of excellent HSPFC programs occupied 63.39% of total constructed areas. Meanwhile, there were two HSPFC programs whose effective evaluation were poor which occupied 4.76% of total constructed areas. The results derived from this study could provide scientific proofs for subsequent construction of High-Standard Prime Farmland.
