Land use practice is considered as the major human behavior of exploring and reclaiming the earth surface features,affecting water flow,land-sliding,soluble nutrient transportation and soil erosion dynamics dominantly.All these processes,however,are believed as the main types of land degradation and environmental deterioration in terrestrial ecosystems,threatening the harmoniousness between human and nature worldwide.Accelerated land use conversion in today’s world may possibly increase the uncertainties and complexities of all these processes,making accurate prediction and hazard control more difficult.Studying land use change and related consequences on terrestrial ecosystems is thus becoming urgent.In general,population expansion,climate change and relevant land policies are considered as three major drivers of land use change,although many other specific factors may also play constructive roles.In order to control the losses and damages of severe water loss,pollution diffusion and soil erosion in the key susceptive regions,scientific planning and careful implementation of land use readjustment are absolutely needed.In this paper therefore,the causes,driving forces and hydrological consequences of land use change on terrestrial ecosystems,were stressed and elaborated.Then,the related countermeasures were also highlighted.It is thought to be of significance for land optimization and hazard control,which is expected to provide references for the scientific communities and policymakers.

建筑和地理环境的关系密切，总结为两个方面，即地理环境对建筑的影响和建筑对地理环境的响应。因而建筑带有明显的地理属性(或者称之为空间属性)，从建筑聚落的组织和空间形态到建筑单体的布局、材料、构造及建造技术和风格，再到色彩和细部装饰，明显带有所在地区的特征，从地理学的角度来看，这是一种建筑风格和形态的空间分异。地理景观的空间分异依存于地理尺度，其在不同的尺度等级上分化为不同等级和规模的区域单元。因此建
