土地利用变化研究现状

采用文献研究的方法,综合叙述土地利用/覆被变化研究20多年来的研究进展,总结土地变化科学研究的新理论与新方法,并展望了未来土地变化科学研究的方向,进一步加强中国的土地变化科学研究。土地变化科学在土地利用数量变化研究、驱动力研究、土地利用变化模拟研究方面取得了丰硕的成果。一方面是驱动力因子的多样性;另一方面是土地利用变化模拟方法的交叉性,已从数量模拟研究转向空间模拟研究,从单方法模拟研究转向多种方法结合的模拟研究,从生物物理驱动力的建模方式转向生物物理驱动力与社会经济驱动力相结合的建模方式。未来的土地变化研究要加强精度的要求,促进土地变化科学的发展,同时其研究成果能真正引导土地利用规划。参46

A review of land use and land cover changes in China

To improve research on land use and land cover changes(LUCC) in China,the literature on LUCC research over the past two decades was reviewed,new theories and research methods were summarized,and further development was predicted.Results indicated that the science of LUCC has made great achievements in its quantitative study,study of the driving forces,and land use simulation.Two important accomplishments were noted.One was the diversity of the driving factors.The other was the interdisciplinary work with LUCC along with new modifications for land use change simulation,including from quantitative to spatial simulations,from single-method to a multiple-method simulations,and from models of biological and physical to models with socio-economic driving forces.However,to promote research development and ensure applicability of the research results, further LUCC research should have higher precision requirements.
