【摘要】： 根据典型干旱区草型湖泊乌梁素海湿地保护区自然、社会和流域特征,在调研的基础上,从资源经济学、环境经济学角度对其价值进行分析,运用市场价值法、分组旅行费用法、生态价值法、影子工程法、炭税法、条件价值法等方法,分别对乌梁素海湿地直接使用价值、间接使用价值及目前非使用价值进行货币化评估,进而得出乌梁素海湿地总经济价值。评估结果表明乌梁素海湿地的总价值为28.24×108元,其中直接实物产品价值为7 164.70×104元,直接非实物服务价值为18 193.43×104元,间接价值为81 960.58×104元,目前非使用类价值为17.51×108元。依据2003年～2005年乌梁素海26个监测点的水质监测结果,选用Logistic Curve(L-C)水环境质量综合评价模型,以等级评价标准和均匀随机数产生建模样本和验证样本,利用实码加速遗传算法求解评价模型,对乌梁素海水环境质量的富营养化进行了现状评价,得出乌梁素海三年的富营养化等级都处于5级极富营养状态。选用L.D詹姆斯的污染损失—浓度模型,根据2003年～2005年乌梁素海实测水质资料,对乌梁素海湖泊使用功能损害程度进行评价表明:乌梁素海水已不适宜作为饮用水源和游泳用水(功能丧失) ,作为人体非直接接触的旅游娱乐用水及渔业养殖用水也受到严重威胁(中损害,2003年为重损害) ,乌梁素海湖水作为一般居住环境用水呈现逐年改善的趋势(重损害→中损害→轻损害),湖泊功能整体损害程度相当严重。以L.D詹姆斯水污染损失率法计算乌梁素海2005年度旅游度假和水产养殖两项使用功能的经济损失,通过对乌拉特前旗水务局、城建局、环保局、巴彦淖尔市农垦局、乌梁素海渔场等单位的调查走访,获得乌梁素海水污染引起的市政工程投资、水污染防御性投资、突发性水污染事故经济损失方面的数据,从而得出乌梁素海2005年度水污染经济损失。基于上述分析,探讨了乌梁素海水环境恢复和重建技术途径,提出从富营养化控制和经济手段、行政手段、法律手段等方面的治理及保护对策。有助于合理开发乌梁素海湿地资源,保护好这一对区域环境具有重要意义
[Abstract]:According to the characteristics of nature, society and watershed in the typical arid region of Wuliangsuhai Wetland Reserve, on the basis of investigation and investigation, the value of Wulangsuhai Wetland Reserve is analyzed from the angle of resource economics and environmental economics, and the method of market value is used. Group travel cost method, ecological value method, shadow engineering method, carbon tax law, conditional value method and other methods are used to evaluate the direct use value, indirect use value and current non-use value of Wuliangsuhai wetland, respectively. Then the total economic value of Wuliangsuhai wetland is obtained. The evaluation results show that the total value of Wuliangsuhai wetland is 28.24 脳 10 ~ 8 yuan, of which the direct physical product value is 7 164.70 脳 10 ~ 4 yuan, the direct non-physical service value is 18 193.43 脳 10 ~ 4 yuan, the indirect value is 81 960.58 脳 10 ~ 4 yuan, and the value of non-use type is 17.51 脳 10 ~ 8 yuan at present. According to the water quality monitoring results of 26 monitoring sites in Wuliangsuhai from 2003 to 2005, Logistic CurveL-C) comprehensive evaluation model of water environment quality was selected, and the modeling and verification samples were generated by grade evaluation standard and uniform random number. By using real code accelerated genetic algorithm (RGA) to solve the evaluation model, the eutrophication of water environment quality of Uliangsu was evaluated. It was concluded that the eutrophication grade of Wuliangsuhai for three years was in the state of extreme eutrophication of grade 5. Based on the water quality data of Wuliangsu Sea from 2003 to 2005, the pollution loss concentration model of L.D James was selected. The evaluation of the damage degree of the use function of the lake in Wuliangsuhai shows that the sea water of Uliangsu is no longer suitable for drinking water and swimming water (loss of function). The use of water for tourism, recreation and aquaculture, which is not in direct contact with the human body, is also seriously threatened (moderate damage, severe damage in 2003), The water of Wuliangsuhai Lake, as a general living environment water, shows a trend of improvement year by year (the damage is heavy damage, the damage is less than the damage, the damage degree of the whole lake function is quite serious. The loss rate of water pollution by L.D James method was used to calculate the economic loss of tourism vacation and aquaculture in 2005 in Wuliangsuhai. Through the analysis of the former Water Bureau, Urban Construction Bureau, Environmental Protection Bureau, Bayannur Bureau of Agriculture and Reclamation, The investigation and visit of the Wuliangsuhai fishing ground and other units obtained data on the investment in municipal works, the defensive investment in water pollution, and the economic losses caused by sudden water pollution accidents caused by the pollution of water by Uliangsu. Thus, the economic loss of water pollution of Wuliangsuhai in 2005 was obtained. Based on the above analysis, the technical approaches to the restoration and reconstruction of the seawater environment of Uliangsu were discussed, and the countermeasures of controlling and protecting eutrophication from the aspects of eutrophication control and economic means, administrative means, legal means and so on were put forward. It is helpful for the rational development of Wulangsuhai wetland resources and the protection of the regional environment is of great significance.
