基于"三调"成果的生态产品基础信息调查技术方法研究OA

Ecological products are a general term for material supply,regulatory services and cultural services provided by natural ecosystems,and are important carriers for realizing the value of ecosystem services.The basic information survey of ecological products can find out the quantity,ownership and spatial distribution of various ecological products,and is the data basis for realizing the value of ecological products.Due to the diversity,complexity and dependence of ecological products,conventional survey methods cannot meet work needs.Diversified survey forms must be adopted to effectively and comprehensively complete the basic information survey of ecological products.Based on the results of the Third National Land Survey(also referred to as the ″Third Survey″),combined with agricultural,meteorological,ecological,forestry and other data,using data analysis methods,multi-source heterogeneous data fusion methods and field addition survey methods means to explore the technical method system suitable for ecological product basic information survey.The results show that the proposed method is highly transplantable and stable,can provide technical support for the investigation and monitoring of basic information of ecological products,provide data basis for ecological product value accounting,ecological compensation mechanism construction,etc.,and solve the problem of ecological products ″difficulty″.
