The water energy resources contained in the areas of Jinsha River, Yalong River and Dadu River of Sichuan Province hold a safe lead and have absolute predominance in the world in either total amount and the average value,and it is thought as the most on the earth,besides these there are mutual conveyance of natural resources among mining,farming, forestry and husbandry,etc..Now the golden delta is still a virgin land to be reclaimed,various resources of water energy,mining and ecology are sunk in sleep.To open the treasure house of resources and to realise the vigorous development of economy in the partial watershed of Sichuan Province or even the whole watershed of Yangtze River,it is needed to catch the key that is to exploit the water energy of the rivers.It is sug- gested:first,to summarize the historical experiences and to take the un- fliching development of water energy in Sichuan Province in priority as the guide policy;secondly,to prepare strongly for the comprehensive exploitation with the greatest effort and all the measures available;third- ly,to reform the system of electricity management,to expand the exten- tion“to support electricity with electricity”,and to soften the policy in introduction of foreign funds.It is said that,only in this way,the ex- ploitation of water energy resource of the three rivers could be accelarat- ed in large scale,realizing the virtuous circulation in ecology.
