摘要:
基于重庆市北碚区l990-2005年土地利用变更数据，运用景观生态学的结构数量分析方法，就重庆市北碚区土地利用结构变化特征进行了研究。结果表明：（1）1990-2005年，多样性指数、多样化指数和均匀度指数总体上呈上升趋势，优势度指数、集中化指数却呈减少的趋势，几个系数间此消彼长的关系基本一致；（2）北碚区土地利用各指数表明其土地利用结构更加趋于平均化和多样化；（3）土地利用类型变化强度表现为：水利设施用地>交通运输用地>园地>林地>居民点及工矿用地>其他农用地>耕地>未利用地。
Abstract:
Based on the statistics of acreages of land under different land use from 1990 to 2005, the variation of land use structure was obtained by the structural quantitative analysis method of the landscape ecology in Beibei district, Chongqing. (1) The index of diversification, diversity and superiority increased, however, the index of homogeneity and centrality declined, and the movements of these indexes were alike on the whole; (2) Those indexes of land-use structure indicated that the land-use structure tended to be more diversified and averaged; (3) The changing intensity of land utilization types was following: irrigation works land > traffic area > garden plots > woodland > industrial and residential areas > other agricultural land > farmland > virgin soil.
