中文摘要	冻融侵蚀区的界定是目前青藏高原冻融侵蚀研究需要解决的重要课题之一。根据笔者和前人相关成果，该文提出了青藏高原冻融侵蚀区界定的理论依据，并在GIS技术支持下，对青藏高原的主体——西藏自治区的冻融侵蚀进行界定，系统分析西藏冻融侵蚀区的分布规律。西藏自治区冻融侵蚀区分布具有以下特点：1)冻融侵蚀区分布面积广，占西藏自治区国土面积的55．3％；2)雅江南北冻融侵蚀区分布差异明显，雅江以北分布范围广，雅江以南范围小；3)地区分布差异明显，冻融侵蚀区集中分布在那曲和阿里地区；4)冻融侵蚀是那曲、阿里、拉萨、昌都、日喀则等地区(市)最主要的土壤侵蚀类型。
英文摘要	This paper takes the Erhai Lake, which is the second bigg est lake in Yunnan Province, as a case study to state the methodolog ies and technolog ies for implementing the information system of the lake v alley administration. Er hai Lake Valley Manag ement Information System ( EHLVMI S) is used to enhance the scientific administration, pro tection and po llutio n pr evention of Erhai lake va-l ley. The EHLVM IS has the follow ing functions: 1) to query the characters of water resources, the status of t he land use, geospatial data and so fo rth; 2) to analyze the ecological environment pollution and chang es; 3) to detect the changes of the water quality and vo-l ume of Er hai Lake throug h the decision support models ( DSM) developed by the authors. The EHLVMIS is designed and developed based on t he technolo gies of remote sensing ( RS) , global position system ( GPS) , geo graphy info rmat ion system ( GIS) , as well as the knowledg e of water r esources and ecolog ical environment. The establishment of t he geospatial data framew ork and DSM for the EHLVMIS is described in the paper. The DSM includes water body model, w ater volume balance and water resour ce dispatch model, w ater quality and zoology contro l model, ecolog ical env ironment evaluat ion model, etc. The three main subsystems, thematic model system, lake valley fundamental GI S and administr atio n information systems of EHLVMIS ar e expressed. The thematic subsystem is the most important among all the subsystems, w hich has the functions of w ater resour ces management and dispatch, model. s management, ecological env ironment management, etc. The softw ar e dev elopment techno logies, database structur es, data classifications and system configuration adopted in EHLVMIS ar e outlined. To elaborate the methodologies of the implementation o f EHLVM IS, the key t echnolog ies of the data mining o f remote sensing imag es, area value inter positio n, automatic wor kflow and spatial- temporal data process are outlined. Finally, the paper discusses the general t heories and technolo gies in the development and applicat ion of lake valley administr atio n information system.
