区域土地利用的社会效益及其时空特征研究

Study on Social Benefit of Regional Land-use and Its Space-time Characters

土地利用的社会效益是社会经济可持续发展的基础。从用地公平、居民生活质量、社会公平和社会保障等四个方面构建土地利用社会效益评价指标体系,采用AHP法、变异系数法和综合评价模型对湛江市土地利用的社会效益进行了评价,并分析了其时空特征。结果表明,1996—2006年湛江市土地利用的用地公平性较高且变化较小,而居民生活质量、社会公平性和社会保障功能都有不同程度的提高,土地利用的社会效益明显增加;2006年土地利用社会效益以遂溪县最高、徐闻县最低。分析了土地利用社会效益的主要影响因素,并提出了相应的对策措施。
