实时、准确地掌握区域水土流失时空变异规律是制定有效水土保持措施的关键.但目前水土流失时空规律分析鲜有兼顾定量数值特征与空间可视化特征.本研究利用探索性空间分析方法和遥感信息，在景观尺度上，对1994~2003年间浙江安吉县水土流失的时空动态格局进行分析.结果表明，10年间安吉县水土流失强度增加、影响范围扩大、水土流失高风险区面积增加.在500 m×500 m和1 000 m×1 000 m 2种格网尺度上，水土流失空间格局均表现出明显的空间集聚性，但以500 m×500 m尺度上的表现更为显著.这种探索性空间分析方法，从定量的统计学和可视化角度有效地揭示了水土流失的时空变异规律，为相关部门和人员定量评价水土流失，制定有效的水保措施提供了新的方法和手段.

Emerging as an urban development mode that attempts to effectively promote the sustainable feedback between land use and transport, transit oriented development (TOD) emphasizes the land use development surrounding the public transit node. Many cases across the world have showed the success of TOD and TOD has been adopted as a policy tool for China􀆳s territorial spatial governance. It requires a literature review to inform the application and practice of TOD in China. From a dual perspective of theory and methodology, this paper systematically reviewed related studies of TOD from four aspects, namely the TOD conceptualization, the typology, the consequences and the optimization. Based on the review, challenges both in theory and in methodology were summarized and implications for China 􀆳s territorial spatial governance were discussed, in order to provide references for formulating efficient TOD planning and strategies.
