Evolution and Analysis of Agricultural Land Use Pattern

ZANG Li-juan et al(College of Geoexploration Science and Technology,Jilin University,Changchun,Jilin 130026)  
Taking Zhenlai County for an example,with three periods of remote sensing images in 1990,2000 and 2006 as the main data sources,under the support of GIS technology,the amount changes of land-use patterns were analyzed by using transfer matrix and the changes of land-use spatial patterns were analyzed by using landscape indices.The results showed that the agricultural land in Zhenlai County from 1990 to 2006 increased and the ecological land reduced.The cultivated land increased on the price of the reducing grassland.The degradation of wetland,the expansion of saline-alkali land,and the water resource environment and its changes directly affected the development of salinization.The land-use landscape patterns were simple,the landscape heterogeneity reduced and it developed towards the artificial ecosystem with simple structure.Based on the statistical data analysis,the land-use pattern of Zhenlai County was stressed by natural factors.The human factors directly induced the ecological environment deterioration.Therefore,the correct directions of land-use were to increase the ecological land and establish a complex ecosystem with agriculture,forestry and animal husbandry.
