Study On The Construction Of Rural Ecological Spatial Network In Yanhe River Basin Based On Water Resources Carrying Capacity

As a complete ecological geographical unit,watershed ecological environment is one of the current hot spots in research.The river basin is the first tributary of the Yellow River,also known as the "Mother River" of the Chinese Revolution.However,the ecological environment is very fragile and water resources are in short supply.With the development and popularization of ecological control projects and high-quality development work in the Yellow River Basin,the environment has been greatly improved.However,in recent years,some rural land has been occupied,resulting in the destruction of rural ecological space in the watershed.Rural ecological network is an effective way to solve the problem of rural ecological space.As the key element of watershed ecosystem,water resources play an irreplaceable role in the stable function of ecosystem and the sustainable stability of ecological space.Therefore,the construction of rural ecological network under the water resources carrying capacity is of great significance to the development of rural ecological space in the Yanhe River Basin.First of all,the research background,sources,research progress and research methods are summarized in order to find a breakthrough to solve the problem.Secondly,through the introduction of related concepts,related research theories,technologies and methods,it provides theoretical and technical support for this research.Thirdly,through on-the-spot investigation and data acquisition,this paper investigates and analyzes the current situation of water resources carrying capacity and ecological spatial elements,establishes a research database,and summarizes the characteristics of rural ecological spatial elements from the perspective of water resources carrying capacity.Fourthly,by discussing the relationship between water resources carrying capacity and rural ecological network in Yanhe River Basin,the rural ecological network construction mechanism under water resources carrying capacity is constructed,and the rural ecological network construction method system under the influence of water resources carrying capacity is proposed.Fifthly,the network analysis method is used to select the optimal scenario scheme of rural ecological network in Yanhe River Basin,and then the network structure of the optimal scenario scheme is planned by using complex network theory,and the main contents and strategies for improving the network function are put forward.Finally,this paper summarizes the conclusions,innovations and shortcomings.Through multi-disciplinary and multi-field research,reference can be provided for the construction and planning of rural ecological network in Yanhe River Basin.By analyzing the present situation and characteristics of "water resources carrying capacity-rural ecological network",the interaction mechanism between them was constructed,and the square system of ecological source node identification,ecological corridor selection and ecological network layout in the three-dimensional space of water resources carrying capacity was established.According to the method system,the scheme of rural ecological network in Yanhe River Basin was obtained,and the ecological network structure of "one axis,three centers,four districts,two belts and multiple nodes" was planned.This paper provides a basis for the research of rural ecological space in the Yanhe River Basin,and also provides reference value for the research of rural ecological network construction in other areas of China.
