摘要:

农地流转已经成为影响中国农业发展的重要因素之一,分析农地流转空间格局特征对中国农业的转型发展尤为重要。本文以黄淮海平原农户调查数据为基础,引入ELL模型对黄淮海平原农地流转抽样数据进行了空间推演,获得该地区县域尺度农地流转方向和规模的空间格局参数,进而通过局部空间自相关分析描述农地流转表征指标在县域尺度上的集聚特征。研究表明:①黄淮海平原县域农地转入规模在440.79~1379.86hm2,呈现出由西向东递增的趋势;农地转出规模在908.61~2745.29hm2,表现出由西北向东南递增的特征;②农地转入和转出的Moran’s Ii值分别为0.78和0.89,反映出黄淮海平原农地转入和转出规模在空间上正相关(HH集聚和LL集聚),且相关系数较高;③在95%的置信度下,农地转入HH集聚区、LL集聚区县域单元数量占比分别为16.67%和20.61%;农地转出HH集聚区、LL集聚区县域单元数量占比分别为19.08%和26.32%;HH集聚的县域是黄淮海平原农地流转的核心区,有着较强的正向效应,LL集聚的县域在空间分布上较集中、稳定,对周边县域有负向影响。该研究揭示的黄淮海平原农地流转空间分布信息或规律,可以为农地流转空间格局优化和相关的管理政策制定提供参考。

Abstract:

Farmland conversions has become one of the most important factors affecting agriculturally sustainable development in China,and spatial patterns of farmland transfer are particularly important to food security. Based on sample data of household surveys,we introduce the Elbers,Lanjouw and Lanjouw’s Method to map farmland conversions in the North China Plain in order to obtain the direction and scale of farmland conversions. Further,we analyzed the aggregating characteristics that refer to index of farmland conversions using LISA. We found that the scale of farmland inflow ranges from 440.79hm2 to 1379.87hm2,and the scale of farmland outflow ranges from 908hm2 to 2745.29hm2. The scale of farmland inflow shows an increasing space situation from west to east. While the scale of farmland outflow shows an increasing space situation from northwest to southeast. The values of Moran’s Ii related to farmland inflow and farmland outflow respectively are 0.78 and 0.89,indicating that the scale of farmland inflow and farmland outflow in the North China Plain have positive associations in space (the HH agglomeration and the LL agglomeration)and both have strong relevance. At the confidence level of 95%,county unit rates of farmland inflow are 16.67% for HH agglomeration and 20.61% for LL agglomeration;county unit rates of farmland outflow are 19.06% for HH agglomeration and 26.32% for LL agglomeration;the counties of HH agglomeration have become the core area in the North China Plain and have a stronger positive impact,meanwhile LL agglomeration has a relatively stable spatial distribution and negative impact. These results will lay the foundation for optimizing farmland conversions.
