Water Resource In ChengDu City Is Comprehensive As Use Continuously To Expound And Prove

Water is strategical economic resource and the natural resource of basicness, is the control essential factor of ecological environment. Water resource can use continuously, is city and even the national economic social guarantee with very important sustainable development, it is also the very important guarantee of maintenance human environment.From plenty of data, investigation and analysis, and in average effective water resource is measured for 179.1700000000 m3s , is foreseen for 2020 years, in the year of Chengdu city (city region ), water requirement is 160.7100000000 m3s. Though, city region annual water resource is measured with annual water requirement is equal approximately, water resource quantity summary is larger than the near 4% of water requirement around, also annual water resource amount satisfy the requirement of water requirement basically, but the Chengdu water with overall city resource situation is do not allow optimistic, and it is still considerable and stern, because use level not high, space-time distribution not , annual occasion change big , water pollution relatively serious. In withered water time, the annual water resource amount of Chengdu city is lower than water requirement, at the same time, it is not even that Chengdu city distribute in the year of water resource forecast year, except the 7 of summer, August and the 9 of autumn , the water resource of October quantity insurable certificate water requirement have greater spare just besides, others not satisfy water requirement in month, what is biggest in which the gap of supply and demand is that in March this month water resource quantity the 47% that has only water requirement , lack 6.8900000000 m3s yet. If not from solution water resource to useful water resource aspect take effective measures words, the water resource of Chengdu city will be very tense.Chengdu city water resource is faced with to fill district, is stressed with water contradiction , water quality and source of water the protective goal in bad, water resource development use unitary , synthesize using few, underground water development pay attention to insufficient, water drought harm is still serious trouble , carry out urbanism bring regulate rivers and watercourses the problems such as new general layout, if go to forecast year without effective measure, the water resource of Chengdu city will be far to can not satisfy water requirement. Suggest from reduceexpenditure prior , treat dirt is , much channel open source; Prevent flood actively to reduce calamity synthesize to administer; Strengthen water resource protect; Guarantee that ecological environment uses water; Improve waterpipe reason system, strengthen the management of water resource; Carry out the water unifinication management of town and country vigorously; With economic measure, establish few aspect take effective measureses such as suitable water price. Eventually, accomplish with water resource the sustainable development that can use support Chengdu city socioeconomy continuously.
