摘    要:高标准农田建设综合成效评估对高标准基本农田规划实施、政府决策等有重要意义。论文基于粒子群优化算法的投影寻踪模型,使用访谈数据、图件数据和统计数据,构建综合绩效评价指标体系,评估样区高标准农田建设综合成效。结果表明:1)与建设前相比,农地平整状况维度中耕地连片度增加13.56%。耕地破碎度呈显著离散性,梯田化率明显提升;农业生产条件维度中道路通达度提升25%,空间离散度略微增加,有集聚效应。道路硬化率建设后分布仍呈中部高、两端低的态势。灌溉保证率和沟渠密度显著增加,空间分布均与南部产业结构、地形密切相关;农田生态环境维度植被覆盖率在建设后空间分布仍呈显著离散性。有效土层厚度明显增加,空间分布格局与道路通达性相当;多主体满意度维度农民满意度和公司企业满足度在空间上均表现为南部鹤大台地区满意度最为明显,农民人均新增年收入建设后空间分布较为均匀。2)Ⅰ级成效区,综合成效评价最佳,4个子目标也引起了足够重视,占比为53.26%;Ⅱ级成效区的综合评价次之,4个子目标的投影值也与之匹配,是高标准农田建设的选址及建成后综合成效凸显的重点区,占比37.62%;Ⅲ级成效区的综合成效相对较差,4个子目标所得投影值也相对较低,占比为9.12%。高标准农田建设的评价,应考虑区域独有特点,制定科学合理的评价程序,有序开展差别化评价。

Abstract:Evaluating the comprehensive performance of high standard farmland construction project has important significance in the implementation of high standard farmland planning and government decision-making. On the bases of particle projection pursuit model (PP) optimized with swarm optimization (PSO) algorithm, investigation data, maps and statistic data of land use were used to build the index system for comprehensive performance evaluation of high standard farmland construction project in Dianjiang County, Chongqing. The results showed that: 1) Compared with the situation before the construction of high standard farmland, the contiguous degree of cultivated land increased by 13.56%, which indicated the improvement of the agricultural land flat condition. After the construction of high standard farmland, arable land showed significant discreteness, and the rate of terraced field increased significantly. The road accessibility also increased by 25%, which showed the improvement of the agricultural production conditions. Spatial dispersion slightly increased and agglomeration effect appeared after the project implementation. Road hardening rate were high in the middle and low at two sides of the area after high standards farmland construction. Irrigation guarantee rate and ditch density were improved apparently after high standards farmland construction, and the improved area was closely related to the industrial structure and terrain conditions in the south. The vegetation coverage rate of farmland ecological environment kept remarkably discrete during the whole process of the project. The thickness of effective soil layer increased obviously, and its spatial distribution is quite related with road accessibility. There existed big dispersion in the improvement of multiple subjects' satisfaction that both individual satisfaction and corporation satisfaction were high in southern crane platform areas after the implementation. The spatial distribution of newly increased annual income was evenly distributed after the high standards farmland construction. 2) As for the comprehensive effect evaluation, the comprehensive effect of Class Ⅰ production area, accounting for 53.26% of the area, was the best where the multiple subjects' satisfaction was promoted, the agricultural condition, the farmland ecological environment and the agricultural land flat condition were all improved. The overall comprehensive effect of Class Ⅱ area, taking 37.62% of the area, was the second where the projection values of the four subgoals matched the effect and comprehensive results will be significant after the completion of the project. The comprehensive effect of Class Ⅲ area, taking 9.12% of the area, was relatively poor where the projection values of the four subsystems were relatively low. Comprehensive evaluation of high standard farmland construction should take unique regional characteristics into consideration, formulate scientific and reasonable evaluation plan, and orderly perform differential evaluation.
