- Abstract:
- This paper quantitatively analyzed the spatial-temporal patterns of land use/cover change, and the spatial transfer trends of centroids of all land use classes in recent 20 years based on three TM images in Augusts, 1990, 2003 and 2010 of Bole reclamation area. We employed Markov chain equation to predict the evolution trend of LUCC in the coming 10 years(2015—2025). Our results showed the LUCC of our study area changed significantly in recent 20 years: (1) the residential lands increased sharply, and were mainly transformed from grasslands and unused lands. Forestlands decreased greatly, and were converted into grasslands. Farmlands and grasslands increased firstly, and decreased slightly later, but generally presented the increase trend, and the water areas reduced slightly; (2) during the period from 1990 to 2003, the amplitude of centroid skewing of our land use classes was small, specifically, except the residential land, the centroid skewing of the other land use classes was all within 10 km, but during the period from 2003 to 2010, the centroids of all land use classes occurred great migration; (3) under the conditions of constant anthropogenic influence, in the coming 10 years, the residential land, farmland and grassland will continue to increase, and the water area, forestland and unused land will continue to decrease, but the variation amplitude of all land use classes will decrease.
