摘　　要： 通过对中国有关区域土地利用变化对生态环境的影响研究成果的分析,从大气环境、水环境、土壤环境、生态系统、生态环境安全、生态环境影响评价等六个方面论述区域土地利用变化对生态环境的影响研究进展,并对其进行了评述,结果表明,国内的研究体系还不够全面与系统,综合研究成功的案例尚不多见;在土地利用变化系统模型方面建树不大;有关土地利用变化生态环境影响评价的研究仍处于探索阶段。今后的研究应结合遥感、GIS技术与数理手段,寻求方法突破,全面、系统研究区域的"土地利用-生态环境效应 -体制响应-土地利用"反馈环,形成完整而系统的研究体系。 Land use and land cover change （LUCC） has aroused increasing attention of scientists worldwide and thus become the hotspot in the study of global change since 1990. It is mainly because the rapid LUCC has evidently affected the eco-environment. So the research of LUCC and eco-environment has been the object and core content of LUCC research. Based on the all-round and systemic analysis of the relevant research results in China, this paper sets forth the progresses in the studies of the effects of regional land use change on eco- environment from six aspects： effects on air environment; effects on water environment; effects on soil environment ; effects on ecosystem; effects on eco-environmental security and the assessment of effects on eco -environment. The following conclusions are drawn up： ①The regional study system is not all-round and systemic; ②The successful cases of comprehensive research about region is very rare; ③The contribution of building model of LUCC system is very limited; ④The study on the assessment of effects on eco - environment is just initiative. Finally, aimed at the problems above, according to the development tendency of international studies on LUCC, the following contents should be emphasized and＇given priority to in coming LUCC study： ①Set up the systematical and united theory system of LUCC research- “land use change - effects on eco-environment-the framework response-land use change” ;②Make efforts to seek the breakthrough of study methods; ③Build the elevation indicator system of effects of land use change on eco-environment; ④Pay more attention to the international study tendency, “from global to regional, from natural to human”; ⑤Based on the comprehensive LUCC study, build the regional ecological production pattern.
