完善龙胜县社会保障体系：乡镇尺度下土地利用多功能评价及权衡与协同关系研究

Improving the Social Security System in Longsheng County: A Study on the Multifunctional Evaluation, Tradeoff and Cooperative Relationship of Land Use at the Township Scale

摘要: 分析龙胜县县域行政辖区管辖范围的六镇四乡，通过构建土地利用多功能评价体系，运用TOPSIS方法，对龙胜县土地使用状况进行了评估，并运用相关分析方法，对不同功能的协同和权衡进行了测算。通过系统聚类分析法将分析区域分为3类。结果表明：1) 龙胜地区的土地生产功能与土地生活功能呈明显的正向相关关系，具有协同作用；土地的生态功能与生产功能、生活功能之间具有显著的负向相关关系，二者是一种权衡关系，其中生产功能与生产功能之间的负向相关关系最大；2) 第一类的乡镇是龙胜镇其土地总体使用功能得分较高；第二类的乡镇有龙脊镇、瓢里镇，土地使用功能总体得分为中度，生态功能未能完全发挥，与第一类城市相比，生产功能、生活功能还有提高的余地；剩余的七个乡镇为第三类，一方面受自然环境、地理条件的影响，另一方面也与乡镇的地位、政府政策等因素密切相关。

Abstract: Analyzing the six towns and four townships under the jurisdiction of Longsheng County's county administrative jurisdiction, the land use status of Longsheng County was evaluated by constructing a multi-functional land use evaluation system and applying TOPSIS method, and the synergy and trade-offs of different functions were measured by applying relevant analysis methods. The analysis area was divided into 3 categories through systematic cluster analysis method. The results show that: 1) the production function of land and the living function of land in Longsheng area are significantly positively correlated and have a synergistic effect; the ecological function of land has a significant negative correlation with the production function and the living function, and the two are a kind of trade-off relationship, among which the negative correlation between the production function and the production function is the largest; 2) the township in the first category is Longsheng town whose overall land use function score The second category of townships are Longji Township and Liao Li Township, whose overall land use function score is moderate, and the ecological function cannot be fully played, and there is room for improvement of production function and living function compared with the first category of cities; the remaining seven townships are the third category, which are influenced by natural environment and geographical conditions on the one hand, and also closely related to the status of townships and government policies on the other hand.
