基于SEE模型的小城镇土地集约利用评价研究——以遵义县为例

文章阐释小城镇土地集约利用的内涵,在此基础上构建"社会-经济-生态"(SEE)模型建立指标体系,对遵义县30个乡镇土地集约水平进行了评价,并对"社会-经济-生态"协调性水平进行分析。结果表明:遵义县各乡镇土地集约利用水平具有明显的地域差异性,南白镇、虾子镇处于高度集约水平;石板镇、泮水镇等处于中等集约水平;乌江镇、尚稽镇等属于一般集约水平;新民镇等土地利用不集约。就协调度分析得出:经济层指数最高,社会层其次,生态层指数最低。总体来说,协调性水平与集约度相关性显著,且两者均表现出较高的空间相关性。并提出土地集约优化利用的对策措施,以期为实现小城镇可持续发展提供理论依据。

EVALUATION ON LAND INTENSIVE USE IN SMALL TOWNS BASED ON THE SEE MODEL*---TAKING ZUNYI COUNTY FOR AN EXAMPLE

This paper expounded the connotation of the land intensive use in small towns, established the index system of land intensive use of "social - economic - ecology" (SEE) in small towns, evaluated the level of land intensive use for 30 small towns in Zunyi county, and analyzed the coordination of social- economic- ecology. The results showed that the level of land intensive use of each town had obvious regional differences. Nanbai and Xiazi town were at high level of intensive, Shiban and Panshui town were at the middle level of intensive, and Wujiang and Shangji town are at the general level of intensive, and Xinmin Town was not intensive. In terms of the coordination degree, the economic index was the highest, social layer was the second, and the ecological index was in the lowest level. Overall, the relationship between the level of coordination and the degree of land intensive useshowed a high spatial correlation.At last,it put forward the countermeasures on optimizing the land use for the sustainable development of the small towns.
