| Hexi region is located northwestward of Gansu province, which is a drought and absent water region, water recourses is an important competent of sustentation system in Hexi inland region, it is effected and restricted the regional economy continually development and food-supplies produce security, and subtend the human-being subsistence circumstance. The characteristic of drought regional water resources is water's resource attribute and environment's constitute element,the few of pluvial disaster, so it is completely possible to be equated the water resources security with water security. The research based on drainage area water resource's utilize or correlative community,economy,environment, actuality and strategic security advisement, using AHP to take multilevel and Multi-target synthetical evaluate for Hexi region three major drainage area's water security actuality ,and advanced countermeasure for drainage area water security construct.Based on the analysis, the main results as follows:1.Based on the water resources strategic security's target and drought regional water resources characteristic, advanced and established Hexi inland region water resources strategic security's Evaluation System, Indicator System can be disport three tier four major genus,in number 21 indexs.useing the Indicator System to take the Evaluation for Hexi inland region three major drainage area's water resources security actuality, gained Shule river is better-security, Hei he in the water resources security's critical state,Shiyan river already insecurity.2.Adopted the regional economic macro theory, Based on the water resources strategic security evaluated conclusion,Water resources carrying capacity Calculation results,enhanced water resources security guarantee's request, The research advanced logical distribution and structural adjustment's emphases of industrial and agricultural industries, vie. Industrial led to the metallurgical industry, Relying on to key enterprises, Comprehensive development of heavy industry, Advancing into deep processing of agricultural products and value-added rolling, Ensure that the development of light industry, We should vigorously develop tourism-oriented tertiary industry; Grain farming practice restrain, restrain summer, the widening autumn, the widening economic and expanding grass policy, Vigorously develop the seed industry, the vegetable industry and grass industry, change dual structure for grains, economic crops to food, economic and feeding ternary structure, According to agricultural and industrial industrial development layout and focus, The proposed layout of town construction.3. According to various basins ecological water demand and artificial, natural Oasis's characteristics and structure, researched Oasis's ecological structure of the allocation of water, According to Basin, the middle and lower reaches of the structure and layout of Oasis, Has proposed the establishment of "three security line of defense" strategy for the protection of water resources system, vie. the Qilian Mountains area to conserve water conservation function, Water recycling protect the safety line of defense; Oasis to adjust the structure and implementation of the corridor efficient water-saving, Plain water resources effectively protect the security of the supply line of defense; In order to restore stability in the Lower Basin water supply and construction to resist invasion and ecological protection zone sandstorms, Protect integrity of the basin water resources ecological services line of defense. Relying on the system proposed the establishment of efficient water works system, a unified management of water resources and establishes sound policies and regulations, such as seven guarantee system measures. |
