摘要
研究目的:综述喀斯特地区在土地利用/覆被变化研究的进展和不足,展望未来研究方向。研究方法:文献综述法。研究结论:⑴中国西南喀斯特地区土地利用/覆被动态变化研究较少,是LUCC研究的薄弱区域。⑵喀斯特地区土地利用/覆被格局和过程变化的研究刚起步,需要深入研究以解释其变化过程和空间差异。⑶在驱动力方面,对城市化、政策、制度以及全球化等因素及它们间如何共同作用于LUCC涉及较少。⑷如何建立具有良好空间表达能力并能反演LUCC历史过程和预测未来变化的模型,有待深入研究。⑸LUCC对区域生态服务功能和人类福利的影响以及人类社会对此如何响应的研究将是喀斯特地区LUCC研究的一个新的方向。
The purpose of the study is to discuss the latest progresses and weaknesses in land use/cover change research in karst areas, and to point out the potential hot fields in the future by reviewing the literatures published over the past more than 10 years. Method of documentation was employed. The study shows that （1） the land use/cover change in southwestern China has received insufficient attention and is a weak area in LUCC study; （2） the study on land use/cover change in karst areas started not long ago, and more works need to be done to explain the process and spatial difference; （3） as far as the driving forces are concerned, the LUCC community should pay more attention to such factors as urbanization, policy, institution, globalization and so on, and how they work together to influence the local land use/cover change; （4） more attention should be paid to establish a spatially explicit model which can well foretell the future land use/cover change; （5） the influence of land use/cover change on local ecological services and human well-beings is going to be a new direction in karst LUCC research.
