Study On Spatial Landscape Optimization Of Agricultural Industries In Soil Conservation Important Ecological Function Areas In The Three Gorges Reservoir Area

At present,the rural revitalization strategy is in a critical period.Industrial revitalization is the basis for rural revitalization,the good ecological environment is the greatest advantage of rural areas,The sound development of agricultural industry space is an effective way to achieve rural revitalization.However,the blind development of the industry may touch the bottom line of ecological constraints,while excessive ecological constraints will restrict the development of the industry.Therefore,it is particularly important to study the relationship between industry and ecological constraints and explore the research on the goal of ’ balancing ecological and economic benefits to maximize the benefits of comprehensive rural space ’ under the background of industrial suitability under ecological constraints.Based on combing the research progress and related concepts at home and abroad.Taking the important ecological function area of soil conservation in the Three Gorges Reservoir area in Chongqing as the research area,the ’ ecology-industry ’ trade-off model is established as the method of agricultural industry space analysis of industrial suitability under ecological constraints,and the industrial spatial landscape optimization strategy and ecological environment optimization model are proposed.Finally,the ’ ecologyindustry ’ trade-off model was used to analyze and apply the Xiazhong Village in Wuling Town in the study area.Based on the analysis results,the optimization design practice of industrial spatial landscape as the leading industry was carried out.Firstly,an "ecology-industry" trade-off model was constructed for the study area,which was applied to the spatial analysis of agricultural industry in the important ecological function area of soil conservation in the Three Gorges Reservoir.The purpose of the model determination stage is to focus on the problems between industrial development space and ecological environment in the study area and to determine the type of villages,and the purpose of the decision stage is to obtain the optimized technical solutions for the optimization of agricultural industry space landscape.Secondly,the agricultural industry space landscape optimization strategy and ecological environment optimization model are studied.Through the construction of industrial spatial analysis methods,combined with the optimization objectives and directions of maintenance-type villages and promotion-type villages,some universal landscape optimization strategies are proposed from two aspects: ’ reducing the ecological load brought by unit agricultural production space ’ and ’ improving the economy of unit agricultural production space ’ and different models of industrial spatial ecological environment optimization were constructed based on the four typical industries in the study area.Finally,taking Xiazhong Village of Wuling Town in the study area as an example,the optimization design practice of agricultural industry space landscape with planting as the leading industry was carried out.The ’ ecology-industry ’ trade-off model was used to analyze the agricultural industry space of industrial suitability under the ecological constraints of the village.It is proved that Xiazhong Village takes the current planting of the longan as the leading industry,and its industrial development and ecological environment protection will be contradictory.It is determined that Xiazhong Village belongs to the promotion village,clarifies the ecological environment optimization orientation,and proposes the production-ecological consistency strategy.The optimization design of industry space landscape optimization design and the overall planning of the village area was carried out.It provided two optimal design schemes of the spatial mode under the guidance of different industrial spatial functions.
