【摘要】：水土流失是一个与生态安全密切相关的重大环境问题,也是社会高度关注的问题,属生态破坏形式之一。水土保持是建设生态浙江的重要基础性工作和浙江省生态文明建设的重要组成部分。安吉县水土保持规划属国民经济和社会发展规划体系,是合理开发利用安吉水土资源、加强水土保持管理的重要依据;对于实现美丽浙江,发展生态经济和改善生态环境等具有重要的研究意义。本论文通过分析研究全国水土保持规划、浙江省水土保持规划、水土保持相关研究成果、安吉县水土保持现状等成果,开展了安吉县水土保持规划研究。考虑到规划基准年等因素,为使规划更具有可操作性,本规划研究实施中充分应用“3S”技术,针对研究区进行了水土流失重点区域的复核调查,明确研究区水土流失现状分布、水土流失特点等内容,并建立了水土保持信息系统。在此基础上,应用水土保持规划原理和方法,综合考虑浙江省主体功能区规划、安吉县域总体规划、安吉县土地利用总体规划、安吉县林业发展规划、安吉县矿产资源规划等各专业规划要求,应用遥感和GIS技术进行了水土流失重点防治区的划分研究。规划针对重点防治区的分布及特点,进行了水土保持规划重点布局,并设定了目标,据此安排了近期水土保持重点项目,进行投资匡算及实施效果分析。规划创新应用了以小流域界线为单元(兼顾乡镇界、村界)进行重点防治区划定,划定了省级重点预防区1块,县级重点预防区6块,面积783.39km2;县级重点治理区2块,面积221.83km2。规划期(2015~2030年)内,完成水土流失治理面积82km2,其中近期(2015~2020年)完成水土流失治理面积48km2。近期安排重点项目4个,投资8716万元。经过实施效果分析,各项工程实施后每年可减少土壤流失量2万t,产生蓄水效益16万m3,有效提升安吉水土保持功能,改善生态环境,具有良好的生态效果,满足安吉生态维护水质维护的水土保持基础功能需求。
[Abstract]:Soil erosion is an important environmental problem closely related to ecological security, and it is also a highly concerned issue in society. It is one of the forms of ecological destruction.Soil and water conservation is an important basic work in the construction of ecological Zhejiang and an important component of the construction of ecological civilization in Zhejiang Province.Water and soil conservation planning in Anji County belongs to the planning system of national economic and social development. It is an important basis for rational development and utilization of Anji soil and water resources and for strengthening soil and water conservation management.It is of great significance to develop ecological economy and improve ecological environment.Based on the analysis of the national soil and water conservation planning, Zhejiang Province soil and water conservation planning, soil and water conservation related research results, Anji County soil and water conservation status quo, the Anji County soil and water conservation planning research was carried out.Taking into account such factors as the planning base year and so on, in order to make the planning more operational, the "3s" technology has been fully applied in the implementation of this planning study, and a review survey of the key areas of soil and water loss has been carried out in the study area.The present situation and characteristics of soil and water loss in the study area are defined, and the information system of soil and water conservation is established.On this basis, applying the principle and method of soil and water conservation planning, considering the planning of Zhejiang Province's main function area, Anji County, Anji County, Anji County, Anji County, Anji County, Anji County, Anji County, Anji County, Anji County and Anji County.According to the requirements of mineral resources planning in Anji County, remote sensing and GIS techniques are used to study the division of key control areas for soil and water loss.According to the distribution and characteristics of key prevention and control areas, the key layout of soil and water conservation planning is carried out, and the objectives are set. According to this, the key projects of soil and water conservation in the near future are arranged, and the investment and calculation are carried out and the effect of implementation is analyzed.The planning innovation uses the small watershed boundary as the unit (taking into account the township boundary, the village boundary) to delimit the key prevention area, delimits the provincial key prevention area 1, the county level key prevention area 6, the area 783.39 km2, the county level key control area 2, the area 221.83 km2.In the planning period (2015-2030), the control area of soil and water loss was 82km2, among which 48km2 was completed in the near future from 2015-2020).Short-term arrangement of four key projects, investment of 87.16 million yuan.Through the analysis of the effect of the implementation, the amount of soil loss can be reduced by 20 thousand tons per year, and the benefit of water storage will be 160000 m3. The function of soil and water conservation in Anji can be effectively promoted, and the ecological environment can be improved with good ecological effect.To meet the basic functional requirements of water and soil conservation in Anji ecological maintenance and water quality conservation.
