中文摘要： 世界尤其是亚洲的梯田稻作景观因其具有生产、生态和美学等多功能价值而成为世界瞩目的文化景观遗产。哈尼梯田景观是云南省哀牢山区典型的多功能农业景观，已于2011年列入联合国粮农组织"全球重要农业文化遗产"试点地，目前正申请列入联合国教科文组织的文化景观遗产名录。项目选择位于哈尼梯田核心区的全福庄河小流域为对象，采用遥感与GIS技术、实地观测和实验、环境同位素采样分析以及图论等方法，通过天然河沟、人工渠系和田埂廊道体系量化分析梯田景观的结构连接度；选择森林、河沟-坑塘草地与人工冬瓜林子流域分析森林区的水文功能连接度；对比分析相邻固化与非固化廊道对水文生态过程的影响；探讨哈尼梯田文化景观的结构连接度与水文功能连接度的相互关系，识别景观连接度的关键区与水源涵养关键区，探索景观结构-水文连接度与景观稳定性的相互作用机制，为梯田安全格局设计和世界遗产保护提供科学指导。

英文摘要： Multifunctional landscape of rice terraced fields in world especially in Asia is increasingly been recoganized as world cultural heritages. Hani Rice Terrace Landscape is a typical multifunctional agricultural landscape in southern Ailao Mountain of Yunnan Province, China. It has been designated as a pilot site of "Globally Important Agricultural Herritage System" by FAO and is applying "World Cultural Herritage List"by UNESCO in this year. Taking Quanfuzhuang river basin in Yuanyang County of Yunnan Province as object, using Remote Sensing and GIS, field observation and experimentation, environmental isotopes/tracing elements as well as graph theory and other methods, this project will quantify the structural connectivtiy by calculate the corridor connevitity of natural river, man-made canals and levees of rice terraced field; Select three sub-basin of natural forest, grassland of river valley-ponds system, and planted young forest to observe the hydrological connectivity of water source area; Analyze the impacts of consolidated channels and levees of rice terraced field on hydrological process,the hydrological connectivity of interaction between surface and ground water; Identify the key areas of self-restraint water resouces and high hydrological connectivity. Discuss the relationship between the structural a
