水土保持工程措施生态服务功能的物质量化分析

Soil and Water Conservation Ecological Service Function Engineering Measures Things Quality Calculation

在中国土壤侵蚀严重的情况下,运用生态服务功能的相关理论可以正确评价水土保持措施的作用,并为合理的生态建设规划提供依据。文章在梳理国内外水土保持工程措施生态服务功能物质量研究进展的基础上,运用经济外部性理论、公共产品理论、生态环境价值、土壤学、土壤地理学、水土保持学、生态经济学的理论等基本理论为依据,根据《水土保持综合治理规划通则(GBT—15772—1995)》和《水土保持综合治理效益计算方法(GB/T—15774—1995)》,借鉴蓄水拦沙指标体系经济参数,对梯田(淤地坝)蓄水与保土量、梯田(淤地坝)减洪与减沙量的生态服务功能物质量进行计算,提出符合实际的解决办法,以期实现水土保持工作的良性发展,为我国水土保持决策部门提供科学的数据支撑。

Taking China＇s severe soil erosion into account, application the related theory of ecological service function can correctly evaluate the effection of soil and water conservation measures and provide the foundation for the reasonable ecological construction planning. On the basis of combing the research progress of ecological service function quality of soil and water conservation at home and abroad, using the theories of economic externality, public production, ecological environment value, soil science, soil geography, soil and water conservation, ecological economics as the basis, according to the documents of Comprehensive Management Planning of Soil and Water Conservation in General （GBT-15772-1995） and Calculation Method of Comprehensive Management Benefit of Soil and Water Conservation （GB/T-15774-1995）, drawing lessons from the economic parameters of water storage and silt detention indexes system, the paper calculates the ecosystem service quality on the quantity of water storage and soil conservation as well as flood and sediment reduction in terrace （dam）. Further, it puts forward to practical solution in order to realize the benign development of soil and water conservation work in China and provides scientific data supporting for decision-making branch.
