The Research On The Appraisal Method Of Water Resources In Lianshan Area Of Huludao City

The article consist of six chapters:preface;essentials;hydrologic essential factors analysis;water resources quantity;water quality;conclusion and suggestion.The appraisal content includes precipitation,runoff and their space-time change law of every key element. That includes the quantity and the quality of surface water and grounder water. That includes usable amount of water resource.According to 45 years (1956-2000) date of precipitation in the area,the normal mean precipitation is 585.5mm. According to 45 years (1956-2000) date of runoff, the normal mean water resource amount of the earth's surface is 239.581 million cubic meters.or annual mean runoff depth is 145.1mm. According to 21 years (1980-2000) date of gounder water resounce in the area,the whole district normal mean amount is 78.199 million cubic meters.The whole district per capita water resounce amount of the whole district is 442.6 cubic meters.The Daughter river , the guzuyingzi river and other all river are in serious degrees of lack of water competence. The Xingcheng river is in extremly degrees of lack water. The Lianshan rivers and Wuli river per capita water amount have already been lower than that of surviving in the minimum line. The normal usable amount of water resource of the earth's surface of 10 years (1991-2000) is 64.733 million cubic meters. The supplying water amount of surface water is 11.481 million cubic meters. The surface water development utilization ratio is 17.7%. The normal usable groundwater amount of 10 years (1991-2000) is 57.394 million cubic meters. The exploiting amount actually of groundwater is 57.101 million cubic meters. The exploiting rate of groundwater is 99.5% .Through statistical analysis, the total amount of water resource in the area is lean towards little even.Water have been polluted seriously.The surface water's utilizing degree is relatively low, and the exploiting rate of groundwater is relatively high. Therefore need to improve the degree of development and utilization of water resources of the earth's surface , and then restrain and reduce the exploiting amount of groundwater resources , limited water resource of sustainable utilization.
