南水北调中线工程对安康市渔业发展的限制性因素

[目的]分析南水北调中线工程因水质保护对渔业发展的影响程度,为陕西省安康市渔业养殖结构调整提供科学依据。[方法]运用文献查阅法和调查法,分析影响安康市渔业发展的限制性因素。[结果]从长远看,水质保护对渔业发展产生积极影响;但从短期来看,则会在年产值、养殖技术选择、消费群体选择等方面形成限制性因素。滤食性鱼类养殖年产值仅相当于投食性鱼类养殖收入的10%,渔业养殖结构调整使安康市渔业养殖收入大幅度下降。[结论]采取政府护水宣传与补偿相结合推动渔业结构调整,科学指导选择优良滤食类鱼种与培训相结合提高养殖技术,政策引导使水产品逐步向市场多元化方向发展等措施促进安康市渔业产业可持续发展。

Restrictive Factors of Middle Route of South-to-North Water Diversion Project on Fishery Development in Ankang City

[Objective] The impact degree of water quality preservation of the middle line of South-to-North Water Transfer project on fishery was discussed to provide a scientific basis for the fishery restructuring of Ankang City, Shaanx Province. [Methods] After reviewing related literatures and investigating into the fishery status, the factors that might limit the development of fisheries in Ankang City were listed and analyzed. [Results] Water quality protection might eventually has positive impact on fisheries development, but at present and in a short term, water quality protection is the limiting factor in terms of annual output value, breeding technology choices, consumers choice and so on. Annual revenue of filter-feeding fish farming is only 10% of the feeding fish farming. Fish farming restructuring leads to the significant drop off of fishery revenue in Ankang City. [Conclusion] To promote the well-being sustainable development of the fisheries industry in the city, measures of government propaganda, scientific guidance and supportive policy should be taken.
