Planning and implementation of dam/reservoir projects has traditionally been prompted by the need for furnishing sufficient quantities of water to meet specific needs such as hydropower generation, irrigation, and flood control, and has generally involved little attention to associated environmental aspects such as effects on water quality and regional ecology. Experience in the developing countries over the past two decades points out the need for marked reorientation in thinking on the appropriate role of such projects and hence in their planning and implementation, to make them truly multipurpose. Because of accelerating population growth, food and energy are emerging as critical parameters in many developing countries. Together with shortage of water in the dry season periods of monsoon climate regions, this makes it mandatory to plan such projects to accommodate all water-oriented needs, including promotion of a gamut of human development values as well as protection of natural resources for sustaining continuing development. By such “total multipurpose” planning, as contrasted to the limited multipurpose planning accomplished to date, the major investments in projects for utilizing scarce water resources can be far more useful in helping solve the critical problems ahead. This will require strict coordination of the existing agencies of most government agencies concerned with water resource development, most of which still function with limited purpose objectives and capabilities.

With the support of GIS technology, in this paper, each index in the evaluation system was set to the spatial expression of 100m×100m grid scale. Subsequently, the spatial principal component analysis and hierarchy process-combination weighting method were used to express the spatial distribution of regional ecology security in study area. Some results show that:(1)The spatial distribution differences of regional ecology security are very obvious. (2)The maximum of SESI is 87.14 in Liangzhou District and its surroundings. Comparatively, the minimum value is 43.96 in north Minqin and edge of Tengery desert. This weakens interaction on ecological flowing in the basin as well as the capacity of ecological restoration between landscape patches. So the polarization of the watershed ecological security will become more seriously. (3)The ecological security and sustainable development of Shiyang River Basin are still in class of III(Threaten security) and class IV(insecurity).
