Title: Land-Use Types Change Characteristics and Spatial Heterogeneity in Bayan of Heilongjiang Province
Abstract: This article take Bayan county in Heilongjiang province as the research area, based on the twelve periods of remote sensing images from 1976 to 2011.To study the quantitative and structural changes, changes in the composition of the different characteristics and spatial pattern characteristics of the study area from 1976 to 2011 by RS, GIS and landscape ecology for revealing the laws of land use change.The results showed that:(1)The main land-use types were dry land and forest land, and the area of dry land was the largest, which accounted for more than 50% of the whole study area. The reductions of the areas of construction land and other type land were the mainly land- use type change characteristics, and resulted in a substantial increase of the area of the dry land in 1976- 2011.The forest land area increased obviously, which mainly transferred from dry land. The area of grass land decreased, which turned into mainly dry land,construction land and other type land. The area of construction land, other type land, water and garden land gradually decreased, and the area of paddy land increased.(2)The landscape apartness index,landscape diversity index and landscape shape index showed a downward trend from 1976 to 2011. In 1976- 1988, 1988- 1999,2000- 2011 three time periods: The distribution of land use pattern of the study area expressed asconcentration-decentralized-concentration.The overall pattern stability demonstrated thestable-unstable-stablecomplex stability characteristics. The pattern shape demonstrated thesimplification-complexity-simplificationcharacteristics.(3)Land-use type changes in the study area in space showing a clear differentiation characteristics in 1976-2011. The Fujiang Township and Songhuajiang Township in the southern region of the study area, the Waxing town in the eastern and Xiji town and Hongguang town in the western were in the most frequent changes of land use types.
