| 摘 要： | 该文在对区域土地资源生态安全概念、内容和目标研究的基础上,探讨了区域土地生态安全评价方法,建立了土地资源生态安全评价的代表性指标体系,并以浙江嘉兴市为例,以嘉兴市土地资源生态安全作为评价的目标层,从自然、经济、社会3个系统层着手,细化研究的层次,通过对评价指标的科学性与完备性等检验,最终从状态层选择了24项变量层指标,构建了适合区域特征的土地资源生态安全评价指标体系;进而运用相关数学方法,计算嘉兴市1991年和1997年各评价指标的安全指数,结合AHP法等确定的指标权重,对嘉兴市1991年和1997年的土地资源生态安全状况进行了综合评价.研究认为,嘉兴市土地资源生态安全状况虽稍有好转,但还处于"较差"的安全状态.

However, ecological security theory of land use and evaluation studies have not been unfold in deed. It seems that the research on land ecological security is almost at the first stage. Based on the analysis of notion, content and object of ecological security, this paper discusses evaluation methods of land ecological security, and attempts to found representative index system of ecological security evaluation of land resources. Taking Jiaxing City in Zhejiang province as an example, from three aspects such as nature, economy, society, inspecting through completeness and the scientificity for evaluation index, altogether 24 indices of variable layer, compose and construct an index system of ecological security evaluation of land resources fit to provincial characteristics. Then it has a comprehensive evaluation in this City on land ecological security of land resources in 1991 and 1997. The Study on the evaluation thinks, though it has some improvement in Jiaxing city, that the security is still in the safe state of "Differ from comparatively ". At last, this paper has an analysis of the actuality of land ecological security in Jiaxing City, and puts forward several critical issues concerning ecological security theory of land use and evaluation. Firstly, draw up land ecological function partition and implement planning of ecological protection. Secondly, develop suburban edge advantage and popularize ecological agriculture vigorously. And finally, propaganda of land ecological protection is developed and land ecological protective legal system is established. |
