摘    要:采用浙江省1990-1999年土地利用现状的用地面积数据作为研究的基础数据与材料,运用景观生态学中有关结构数量分析的方法,进行研究区不同时期土地利用结构分异的定量分析,借助于种群生态学中生命表的分析方法进行不同时期土地利用动态变化分析。研究结果表明:(1)采用研究方法能较好反映研究区不同时期土地利用结构分异及其动态变化;(2)研究区土地利用的多样性指数、优势度指数和均匀度指数的变化均是逐渐升高,到1990-1999年间的某一年达到最高值,然后逐步收敛,渐趋稳定,并做小幅度的上下振动,这表明浙江省土地利用结构渐趋稳定;(3)研究区从1990-1999年,各土地利用类型变化强度是林地>园地>牧草地>居民点与工矿用地>交通用地>耕地>水域>未利用地,从土地利用变化的整体上看,园地、居民点及工矿用地和水域面积的增加主要是通过开发未利用地来进行平衡,浙江省土地后备资源短缺的问题将越来越突出。

关 键 词:土地利用结构  时间分异  土地利用动态变化

Abstract:Based on the data of land-use acreage of Zhejiang province from 1990 to 1999 and adopting the quantitative analysis of landscape ecology and life table analysis of population ecology, this paper studies quantitatively the temporal division of regional land-use structure and its dynamic changes in different periods. The results showed that (1) the study methods mentioned above can well reveal the temporal division of regional land-use structure and its dynamic changes; (2) The indexes of diversity, superiority and homogeneity of the land-use structure in the area studied increased steadily and reached their maximum somewhere between 1990 to 1999, followed by a gradual decline until a relative stability with only a slight fluctuation, suggesting that the land-use structure of Zhejiang province has been gradually stabilized; and (3) the intensity of change in land-use in 1990-1999 in the province appeared in the sequence of woodland > garden plots > grassland > industrial and residential areas > traffic area > cropland > water area > virgin soil. On the whole, the increase in the acreage of garden plots, industrial and residential areas and water area was achieved by exploitation of the virgin soils and thus the shortage of reserve land resources will become increasing severe in the province.
Keywords:land-use structure  temporal division  dynamic change in land-use
