《Site Selection of Land Consolidation Project Based on Farmland Quality Evaluation in Yanjin County of Henan Province》
Based on the calculated average national classification index of farmland,the farmland was divided into corresponding national natural classification,national use classification,and national economic classification.Taking the national use classification as an example,we analyzed changes in each project area after the land consolidation projects.The changes in national classification index and average national use classification were listed in Table 4.After the implementation of the consolidation projects,the average national use classification index of all project areas had certain level of increase,Dongtun area and Yulin area had the largest increase(by 153 and 127 respectively),and the corresponding average national use classification increased one level.The comprehensive production conditions(such as drainage conditions and probability of irrigation)of these two areas were worse before consolidation,thus the improvement of farmland production conditions was most effective after consolidation.For Wanglou area and Weiqiu area with excellent field production conditions before consolidation,the consolidation projects had limited improvement effect and mainly played the role of consolidating the original productivity.The average national use classification index showed certain increase,but there was no change in average classification.
