| 摘 要： | 以1998年至2008年韩城市土地利用变化调查数据为基础资料,运用景观生态学中的多样性指数、优势度指数和均匀度指数等有关数量结构分析方法,对韩城市近十年来的土地利用结构的变化进行了定量分析.结果表明：（1）1998-2008年,韩城市各种土地类型变化的强度依次是：交通用地〉耕地〉林地〉其他农用地〉居民点及工矿用地〉园地〉未利用地〉水利设施用地〉牧草地〉水域.（2）1998-2006年韩城市土地利用结构变化明显分为两个阶段：第一阶段1998-2006年,韩城市耕地、林地、未利用地对土地利用的控制程度加大,土地利用多样性减少,各种土地利用类型的面积比例差异加大;第二阶段2006-2008年,韩城市土地利用趋于多样化和平均化.（3）研究表明景观生态学数量结构分析方法能较好地解释近年来韩城市土地利用结构变化的规律,而韩城市适宜的多样项指数、均匀度指数和优势度指数还有待进一步研究.

| Abstract: | Based on the changing data of land utilization in Hancheng city from 1998 to 2008,this study gives a quantitative analysis of the land utilization structure differentiation by using the diversity index,dominance index and evenness index of landscape ecology.Research results showed that：（1）from 1998 to 2008,the changing intensity of various land utilization types in Hancheng is： transportation land cultivated landforest landother agricultural land residential area and industrial land garden plot unused land irrigation works landgrass land inland waters.（2）From 1998 to 2008,the land utilization structure changed in two distinct stages： first phase,from 1998 to 2006,the index of diversification,diversity and superiority declined,however,the index of centrality and homogeneity increased,it indicates that the diversity of land use structure in Han cheng is reduced,the differences in the proportion of various land utilization types in Hancheng is increased;second phase,from 2006 to 2008,the changing trend of Hancheng land utilization tends to be diversified and equalized.（3）The result shows that the quantitative structure configuration method in landscape ecology can better unveil the changing rule of recent years＇ land utilization in Hancheng,yet the appropriateness of the diversity index,dominance index and evenness index in Hancheng needs further study. |
