| 摘 要： | 应用GIS空间分析方法研究撂荒地微观空间分布特征,为解决撂荒地提出了有操作性的对策;同时,采用GIS空间分析法和文献资料法对撂荒地空间分布特征进行了研究。研究结果:一是撂荒地主要分布在远离场镇、交通条件差、灌溉设施缺乏、坡度较大、土地肥力低的地方;二是水田撂荒少,旱地撂荒多,道路交通两侧表现得最为明显;三是撂荒地分布和坡向无显著相关性。研究结论:一是加大基础设施建设,改善生产条件;二是大力调整农业产业结构,做到地尽其用;三是创新土地流转方式,推动适度规模经营;四是改革农地产权,建立退出机制。 |

| Abstract: | The purpose of this paper is to study the spatial distribution characteristics of abandoned cropland with spatial analysis of GIS to provide policy solution of abandoned cropland problem.Method of spatial analysis of GIS and documentation are implied.The result of study indicates that:(1) where abandoned cropland allocated in is where far from town,poor traffic conditions,lack of irrigation facilities,steep slope and low soil fertility;(2) there is less paddy and more dry land which are abandoned especially... |
