| Abstract: | By using RS and GIS technique and the materials from field survey and visiting peasant households at representative regions, the spatio-temporal changes of land-use in the Chashan watershed are analysed from the point of view of human geography. The results show that the cultivated land area in the watershed has dropped to a small extent, the areas of forest land returned from grain plots and the garden land have increased, unused land area has also dropped, and the built-up area has slightly risen. The driving forces that lead to those changes include natural factors and humanistic factors, and the latter is more important. The humanistic factors in the Chashan watershed are the increasing needs of human's survival and consumption, the change of land policy and environmental protection policy, the adjustment of industrial structure, the development of market economy, and the construction of infrastructure. It is considered that developing economy, and developing science and education to raise local people's living level and improve their life quality, are key factors to make full use of land resource and promote the sustainable development of the watershed. |
