青海省耕地利用变化区域差异及管理对策研究
- Title:
- Research on Regional Differences of Cultivated Land Changes and Countermeasures in Qinghai Province
- 分类号:
- F301.2
- 摘要:
- 基于青海省土地利用变更调查序列数据，选取耕地增减情况和建设用地占用耕地情况分析青海省耕地的数量变化特点，并从耕地变化区位差异和耕地增减情况差异出发，分析了全省耕地变化的区域差异特征。结合青海省耕地变化的特点和区域差异特征，提出了针对性的耕地管理对策。研究结果表明：（1）耕地资源主要集中在西宁市和海东地区，土地开发整理是青海省耕地增加的主要来源，而耕地减少主要源于生态退耕和建设占用；（2）耕地占用审批以后，耕地占用存在一定的滞后性，这在一定程度上影响了当年耕地占用计划的制定；（3）对于耕地保护工作而言，要始终坚持最严格的耕地保护制度，坚持差异化的耕地利用政策。
- Abstract:
- Based on the annual survey data of land use changes in Qinghai, we analyzed the change characteristics of cultivated land quantity by taking the situation of cultivated land increase or decrease and cultivated land used for construction into consideration. And in terms of the regional differences in cultivated land changes and the difference of cultivated land increases, we also analyzed the regional features of cultivated land changes in Qinghai. On the basis of these analyses, we put forward different management strategies. The results showed that: (1) cultivated land resources mainly concentrate in Xining city and Haidong district, land management and consolidation were the major source of new cultivated land, while ecological restoration and construction were the major forces driving cultivated land loss; (2) farmland occupation was usually delayed after getting approval, which had a big impact on farmland occupation plan in the year; (3) in order to protect farmland in Qinghai, we should stick to the most stringent farmland protection laws and should carry out the differentiated land use policies.
