| 摘 要： | 从流域系统经济过程的增长度 (IE)、社会过程的满足度 (IS)和自然过程的持续度 (IN)出发 ,提出流域系统可持续发展的综合评价指标 :发展度 (ID)即ID=I2 E+I2 S+I2 N3 、协调度 (IH)即IH=1 -(IE- I) 2 + (IS- I) 2 + (IN- I) 23 和耦合度 (IC)即IC=12 (ID +IH)。最后 ,给出相应的动态评判准则 :强持续性评判准则即YID(t2 ) >YID(t1 ) ,且YIH(t2 )≥YIH(t1 ) ;弱持续性评判准则即GID(t2 ) >GID(t1 ) ,且GIH(t2 )≥GIH(t1 )和持续性评判准则即IID(t2 ) >IID(t1 ) ,且IIH(t2 )≥IIH(t1 )。

| Abstract: | Based on increment degree of economic process (IE), satisfaction degree of social process (Is) and sustainability degree of natural process (IN) of watershed system, the paper puts forward synthetic appraisal indexes of watershed system sustainable development:development degree, namely ID=√I2E+I2S+I2N/3,harmony degree, namely IH = 1and coupling degree, namely Ic=1/2(ID+IH). Finally, the paper points out dynamic judgement criteria of watershed system sustainable development that are strong sustainable riterion: "YID (t2)＞YID(t1) and YIH (t2)≥YIH (t1)", weak sustainable criterion: "GID (t2) ＞GID (t1) and GIH (t2) ≥GIH (t1)", and sustainable criterion:"IID(t2)＞IID(t1) and IIH(t2)≥IIH(t1)". |
