【摘要】：為了評價寶雞地區(qū)近年來的水資源承載力狀況,指導該地區(qū)水資源的可持續(xù)開發(fā)利用,將投影尋蹤法和物元可拓理論進行結(jié)合,建立水資源承載力物元可拓模型,利用投影尋蹤法計算指標權重,消除主觀判斷對評價結(jié)果造成的偏差。選取4個年份作為水平年序列對寶雞地區(qū)水資源承載力進行評價,采用局部靈敏度分析方法對評價結(jié)果進行了準確性驗證。結(jié)果顯示:寶雞地區(qū)2000年水資源承載力處于強無壓力狀態(tài)向平衡狀態(tài)過渡的階段(Ⅱ級),2005和2015年處于平衡狀態(tài)(Ⅲ級),2010年處于弱壓力轉(zhuǎn)態(tài)(Ⅳ級)。隨著經(jīng)濟社會的進一步發(fā)展,應結(jié)合水資源承載力評價結(jié)果,制定科學合理的水資源利用方案,促進水資源與經(jīng)濟社會協(xié)調(diào)健康發(fā)展。
[Abstract]:In order to evaluate the carrying capacity of water resources in Baoji area in recent years and to guide the sustainable development and utilization of water resources in this area, the projection pursuit method and matter-element extension theory are combined. The matter-element extension model of water resources carrying capacity is established, and the index weight is calculated by projection pursuit method. To eliminate the deviation caused by subjective judgment on the evaluation results. 4 years were selected as horizontal year series to evaluate the carrying capacity of water resources in Baoji area. The method of local sensitivity analysis was used to verify the accuracy of the evaluation results. The results showed that in 2000 the water resources carrying capacity in Baoji area was in the stage of transition from strong pressure free state to equilibrium state (stage 鈪，
