Résumé
Desertification is a common major environmental problem currently confronted by human society. Kubuqi desert in history used to be an area with forest and grassland. Due to warfare and excessive felling, farming, and grazing, the original vegetation cover has been destroyed, resulting in severe desertification. The growing desertification is the main ecological problem restricting regional economic development, also responsible for the deteriorating environment and poverty of local farmers and herdsmen. While the state attach great importance to desertification prevention and control work, some achievements have been made after years of efforts, but the work is still tough because of overpopulation, animal overloading, incompetent management, etc. Kubuqi desert regions are ecologically fragile, but also economically underdeveloped and ethnic minority distribution areas. To handle well the relationship, not only relates to the alleviation of poverty, but also relates to the regional environment improvement, national unity and social stability. It provides important theoretical and practical basis for desertification control to study the current distribution of desertification and trends of its change. The paper integrated current situation of Kubuqi desert and its control measures as research object, evaluated desertification and its mechanisms, analyzed and summarized approaches of desertification control and its problems, explored sustainable means for regional development. The major findings are as follows :(1) Based on analysis of the collected geology, geomorphology, soil, climate, hydrology, vegetation data, the regional natural conditions in Kubuqi determine its ecological fragility, vulnerable to desertification. Selecting recent 18 years multi temporal TM image data of study areas, by the interpretation of the images, different periods of desertification grade distribution maps have been obtained. Desertification dynamic process was analyzed in terms of desertification area change, the development rate, transfer characteristics ; spatial changes of desertification levels. The results show an obvious downward trend of total desertification area since 1989. In view of the spatial variations of desertification levels, the desertification is reversed in most areas along the main course of Yellow River, but increased in southeastern, southern desert hinterland, as well as the surrounding of Haizi(lakes). It is obvious that since the 1990s, this region has achieved remarkable progresses in combating desertification and desertification levels decreased. The results indicate that frequent human activities will speed up the desert ecosystem degradation and deterioration of Kubuqi desert where environmental capacity is small.(2) Based on the analysis of existing desert control industry and problems, an industrial desert control model is proposed, which combines desert development and tourism industry. In addition to general engineering, biological measures, the root causes of irrational human activities should be eliminated in order to maintenance dynamic balance of ecological systems and human environment. The desert area is rich in tourism resources, the tourism and ecological construction can help with each other forward. By restrictive tourism development in desert area, let desert tourism as a win-win industry with nature conservation and economic development, in order to improve regional sustainable economic development.(3) Ecotourism planning has been discussed, on the basic theories including landscape ecology, aesthetic, ecological economy, sustainable development .GIS databases of tourism planning in the study area have been established, using analytic hierarchy process (AHP) method, the evaluation of Seven Star Lake scenic area tourism resources were conducted. SWOT method was adopted in comprehensive analysis and evaluation of tourism development conditions, in analysis of regional tourism resources and location advantages, as well as the opportunities and challenges of tourism development. Based on GIS spatial and network analysis tools, using the law of diminishing spatial distance, travel competition and gravity model, tourist market was classified. And then combined with statistical information the market has been predicted.(4)On analytical basis, the park is positioned as a world-class desert conference exhibition and athletic resorts, a world-class comprehensive digital desert demonstration garden. According to the plan area terrain conditions, distribution of tourism resources, traffic location, target market and other factors, considering the park’s strategic development pattern, spatial patterns planning was made for the whole area and zoning planning for different regions, while conceptual planning for key projects, also put forward scheme of monitoring system planning to achieve sustainable development.
