Abstract

Abstract: Based on the land cover data of GlobeLand 30 in 2000 and 2010, taking Qianjiang in Hubei province as the research area,the soil spatial and temporal variation characteristics of cultivated land in Qianjiang is analyzed. And the arable land patch area and the fragmentation index of 19 towns in the city are calculated. The cultivated land area and the fragmentation coupling mode of 9 kinds of cultivated land change are established. The changes in cultivated land, cultivated land fragmentation country towns and the characteristics of both associated with formation of the farmland change are analyzed. The results show that the total cultivated land area of Qianjiang remained stable from 2000 to 2010, but the variation range of the cultivated land area of each town and town within Qianjiang was significant, and the cultivated land fragmentation was intensified. The cultivated land change pattern of “the reduction of cultivated land area with the increase of fragmentation” is dominant in Qianjiang, and it is located in the northeast region where urbanization is developing rapidly. The townships with the pattern of “increase in cultivated land area with reduced fragmentation” are mainly distributed in the southwestern regions where agriculture is relatively developed. The urban construction land gradually occupied the cultivated land in Qianjiang, resulting in a sharp decrease in the area of cultivated land at the edge of the city, and the internal fragmentation trend of the cultivated land is serious.

Key words: cultivated land change, fragmentation, landscape pattern, Qianjiang city
