- Abstract:
- We took Ning’an City in Heilongjiang Province as the study area. Based on the three periods of remote sensing images from 1991 to 2010, we investigated the quantitative and structural changes, land use changes characteristics using the fractal theory of the study area by RS, GIS, spatial statistical analysis and synthesis factor analysis method in order to reveal the pattern of land use change and its influencing factors. The results showed that: (1) drung the period from 1991 to 2010 land use in the study area generally changed, farmland and construction land area increased year by year, decrease of the area of woodland and grassland, water was found, and the other land area remained relatively stable, increase of arable land mainly was shifted from woodland; incremental construction land was mainly shifted from farmland, forestland transfer direction was mainly towards farmland, and was mainly shifted from its incremental grassland, grassland decreased year by year, its main transfer direction was towards farmland and woodland, its increment was mainly shifted from woodland; (2) during the period from 1991 to 2010, Ning’an overall value of the fractal dimension rose, the stability presented the downward trend, the spatial structure of waters was the most complex, spatial structures of arable land and the construction land were relatively simple, structure of waters was most stable; farmland and woodland structures tended to be stable after the first complexity; structures of grassland and construction land were more complex, and tended to be unstable; simple structure of other sites tended to be stable; (3) the main natural factors of land use change were the hydrological and climate characteristics, government decisions affecting land use change direction, the socio-economic development, demographic factors and technological progress were the main driving forces on human land use change, human factors driving strength became great year by year.
