湖北省农用地整理综合效益评价——基于灰色关联方法

Comprehensive Benefits of Farmland Consolidation in Hubei Province

本文运用灰色关联分析方法,通过构建假想的综合效益最优的湖北省农用地整理情形,计算各地级市的实际整理情况与最优情况的关联度,评价湖北省农用地整理的综合效益。研究结果显示,湖北省的农用地整理综合效益显著,但各地级市农用地整理综合效益的地域特征并不明显。灰色关联分析方法可实现对不同项目甚至不同地区土地整治综合效益的大小排序,从而对土地整治规划确定整治目标和整治顺序提供依据。在本轮规划的编制中,应首先重点考虑排序靠前的地市的农用地整理,保证其资金供给。

Land consolidation is the important new platform of rural construction and urban and urban-rural development. Increasing the quantity and quality of cultivated land, along with the ecological environment are the new objectives of land consolidation in China. Hubei province is located in central China and a major grain producing area. Using agricultural land consolidation data for Hubei province over three years and 17 evaluation indices, the economic, social and ecological benefits were selected to establish an evaluation index system. Gray relational analysis was used to evaluate the comprehensive benefits of farmland consolidation in Hubei province. We constructed optimal conditions of farmland consolidation and concluded the association between the actual consolidation situation of each city with the optimal one. The comprehensive benefits of farmland consolidation in Hubei province are significant, for example, the increased cultivated land rate was maintained at 3%-4%, productivity improvement rate was 10%, new cultivated land per ten thousand CNY of investment can support 1500 people, and the average increase rate of green vegetation coverage was improved 2.3%. The order of agricultural land consolidation comprehensive benefits in Hubei from high to low was： Xiangyang Wuhan Huanggang Ezhou Xiaogan Xianning Shennongjia forest region Yichang Suizhou Huangshi Shiyan Xiantao Jingmen Enshi QianJiang Jingzhou Tianmen. The benefits in the mountains of northern Hubei were average, probably because of the huge potential of agricultural land consolidation in this area. Since the natural farming condition of Xiantao, Qianjiang, Tianmen and Jingzhou （representations of Jianghan Plain） is already high, farmland consolidation did not play an important part in improving agricultural comprehensive efficiency in these four cities.
