摘要
首先介绍土地利用变化对大气、水、土壤和生物等环境单要素影响的研究内容和方法;然后从景观生态格局、物质能量流动和生态服务价值等方面综述土地利用变化对区域生态系统综合影响的研究进展;最后针对现有研究的不足,提出加强学科综合交叉研究、注重多尺度的集成、完善"3S"技术与模拟模型的融合及加强生态环境效应反馈机制研究等建议。
A review of impacts of the land use change on the single environmental factor as atmosphere, water, soil and organisms is given. The research progress of comprehensive influences of land use change on regional ecological system from the aspects of landscape ecological pattern, material energy flow, and ecological service value is summarized. Aiming at the shortages of the research, the authors put forward the prospects of the enhancement of cross-over study, the integration of multi-scale, the perfection of the blending of 3S technology and stimulation model, and the strengthening of study on environmental effect feedback mechanism.
