| 3 | Discussion on Landscape Ecosystem Planning of Small Basins in the Qinghai-Tibet Plateau——Taking Nieruzangbu Basin as an Example显示文摘In this paper, taking Nieruzangbu as an example, it is discussed that how to plan landscapes of small basin in the Qinghai-Tibet Plateau. With analyzed the status and character of landscape structure through the use of landscape diversity indexes and landscape dominant indexes, some major problems in the landscape ecosystem are pointed out. On the basis of regional restrictive principle and compliance principle of resources, environment and economy, Nieruzangbu Basin is divided into three landscape function areas. According to the demands of each function area, landscape structure planning is carried out to improve ecological environment through optimization and adjustment of landscape structure in Nieruzangbu Basin. | G He Xiao-rong, Li Hui-xia, Li Ai-nong, Zhou Hong-yi, Wang Xiao-danInstitute of Mountain Hazards and Environment.

| 4 | Systematic Design and Coordination Acts of Ecological Security in Upper Yangtze River in China显示文摘In this paper, systematic design and act of eco-security is discussed as a focal point of conflict and unrest. The situation of ecosystem, the schematic framework of eco-security design, the main acts of ecosystem improvement, major difficulties and challenges have also been analyzed. The purpose of this study was to formulate the systematic framework of eco-security maintenance, to highlight systematic idea or philosophy of ecological rehabilitation and eco-security. A three-dimensional schematic model is applied to design the security of ecosystem. It was concluded that: 1 ) maintaining ecological security requires far better and sophisticated resource management skill and ecological improvement measures, and is also a continuing and multifaceted task. It cannot be permanently accomplished by a single action and program; 2) at present, technical system and policy and law system dimensions of ecological security are not enough even in short; 3)development of ecological industries is beneficial to local economic development and ecosystem protection. | Fang Yi-ping, Chen Quo-jieInstitute of Mountain Hazards and Environment, Chinese Academy of Sciences, Chengdu 610041, Sichuan.
