Abstract:

In order to alleviate land use conflict and manage land efficiently, the authors select the typical area of Yanchi County of Ningxia Province as a case, use the LUCIS conflict identification model based on TM data and social economic data, and build a land use tendency evaluation system of construction, agricultural and ecological land. By means of the conflict discrimination matrix, the potential land use conflict types are recognized and potential land use conflict zone in Yanchi County can be divided into 4 types, including dominant area, weak conflict area, moderate conflict area and intense conflict area. Then it is divided into 12 types of conflict zone according to the combination of land use tendency. The result show that 58.90% of the total area faces a risk of potential land use conflict, mostly of moderate conflict, and mainly for the conflict between construction and agricultural land, agricultural and ecological land and conflict among the three types of land use; 6.82% of the total area faces a high risk of potential land use conflict, mainly for the conflict between construction and agricultural land, agricultural and ecological land; 40.88% of the total area belongs to dominant land use area. According to the actual field survey and nearly ten years of policy and system files, driving factors of the conflict are analyzed, and based on the stakeholder analysis, balance strategies for different types of land use conflicts and land use management suggestions in recent and long-term of the county are proposed. This research explores the mutual influence and potential conflict areas of construction, agricultural and ecological land in desertification area, and the contents and methods are as complementary to land use conflict identification, not only having a breakthrough in the research methods of land use related issues, but also of practical significance for the maintenance of ecological security and sustainable social and economic development in desertification area.

Key words: land use conflict, land use tendency, desertification area, Yanchi County, interest trade-off

摘要：

选取荒漠化、土地利用冲突典型的宁夏盐池县为案例, 采用改进的LUCIS冲突识别模型, 构建基于建设、农业和生态用地倾向的3层潜在土地利用冲突评价指标体系, 借助冲突判别矩阵, 识别出4种潜在冲突类型区: 用地优势区、冲突微弱区、冲突一般区和冲突激烈区; 在此基础上, 又依据用地倾向强度级别组合, 细分为12种冲突类型。结果表明, 盐池县有58.90%的土地存在潜在土地利用冲突, 冲突等级以一般为主, 主要为建设用地与农业用地冲突、农业用地与生态用地冲突和三类用地的相互冲突; 有6.82%的区域发生冲突的风险性高, 主要为建设用地与农业用地间的冲突、农业用地与生态用地间的冲突; 另有40.88%的土地属于用地优势区。结合野外实际调研及近十年政策和制度研读, 对冲突的驱动因素进行分析, 并在利益相关者分析的基础上, 提出各类土地利用冲突的权衡策略。在生态脆弱地区建设、农业和生态3种类型用地潜在冲突识别及利益权衡方面进行了探索, 研究结果对维护荒漠化地区生态安全及社会经济可持续发展有现实意义。
