Study on Cooperative Construction of Ecological Management and Green Infrastructure in Desertified Areas -- A Case Study of Ulan Buh and Sandy Area

The Ulan Buh Desert is located at the edge of the arid zone in the central Eurasian continent, which is one of the main sources of the Yellow River sediment and sandstorms in Northeast Asia. The project site, at the junction of the Ulan Buh Desert, the Hetao Irrigation District and the Yellow River Beach, has abundant groundwater source, unique geographical landscape and sensitive ecological environment. any changes in the regional ecological pattern may lead to significant impacts on the living environment of hundreds of millions of people within tens of millions of square kilometers in the middle and lower reaches of the Yellow River. However, in the past, ecological management, economic development and the construction of human settlements in local area have worked independently. Traditional grazing-based production ways and disorderly scattered settlements consume huge natural resources, leading to the continuous spread of desertification and the increasingly harsh human settlement environment. Therefore, through the construction of a comprehensive and sustainable desertification spatial management system with the whole process of "resource evaluation-green infrastructure construction-landscape performance monitoring", we can solve the contradiction between the abundant natural resources, the fragile ecological pattern and the need to improve the human settlement environment in this area. Firstly, we obtained index information through remote sensing images and big data and quantified indexes through GIS, to construct the technical system of territorial spatial identification and landscape evaluation system. Then, based on desert, we built three systems, an ecological landscape infrastructure system, a vertical circular agriculture system and an efficient and centralized human settlement environment construction system, to realize the sustainable development of local "ecology-production-life". Finally, we monitor the landscape performance of desertification control through the construction of a comprehensive, scientific, parameterized and multidisciplinary dynamic, "sky-air-ground" integrated ecological monitoring system. The desertification spatial governance system achieves a high degree of integration of multiple landscape elements, which ensures the beautiful prospects can be realized mostly through a natural-driven sustainable process. What’s more, this system connects the management system and ecological management of multi-scale and multi-level, to realizes the transmission and implementation of the planning results. Finally, the system achieves the joint promotion of socio-economic, ecological issues and living environment simultaneously in ecologically sensitive desert areas.
