Study On The Sustainable Development In The Sand-Desertification Region, China

The sand-desertification is one of main types of the desertification in China. Although sand-desertification has been controlled for a few of decades, little was reduced and trends to continue enlargement in the areas of the sand-desertification in China. There have been some problems in controlling and preventing sand-desertification process in China. This thesis tried to study controlling and preventing of the sand- desertification in China with the sustainable development and taking a example of the Naiman county, Keerqin sand-desertification region, China.Keerqin sand-desertification region sits on the ecotone zone of agriculture and pasture in the North China where is Vulnerable in natural environment conditions. From the rich of the lands with a plenty of arable and fertile soils and agriculture and pasture with good enough of water sources and grasslands were developed many years ago to the sand-desertification has been getting gradually due to the human anomalous activities in the land use. It is damaged in the Keerqin sand- desertification region not only, in the Northeast China by the environmental destruction resulted from the sand-desertification but also. Therefore it is necessary to study the sustainable development in the sand-desertification region, which is both the development of the Keerqin region and its neighborhood areas (such as Beijing, Northeast China). Little information on the sustainable development in the sand-desertification region has been known. It is very importance for the theory and practice of the sustainable development in the sand-desertification region. The thesis has been directed by the sustainable development, eco-economy, restorative ecology and so on. And investigation in the practice, 3S techniques, AHP and statistics etc. methods were employed in following as:1. The dynamic of the sand-desertification has been analyzed based on the data of 40 years in Naiman County. Results showed that it was much more correlation for the relationship between the sand-desertification and human activities and socio-economic conditions although the materials source of the sand-desertification was from natural environments. Study of the formation and cause of the sand-desertification has been developed from the natural environmental conditions to the human activities and socio-economic conditions. Thus the formation and causes of the desertification are much more concerned in the old socio-economic condition that is the main force factor.2. The sand-desertification was one of the land degenerations resulted from old socio-economic conditions and anomalous human activities. To control and prevent the sand-desertification it is necessary to improve eco-environment based on the sustainable development, restorative ecology, eco-economy and so on the theories. According to control process of the sand-desertification is the sustainable development process in the sand-desertification region a conceptual model of the sustainable development in the sand-desertification region has been proposed, which included the sand-desertification extent, natural environmental factors, human activities and socio-economic conditions. The relationship between them is undividual and improvement and mosaic of each other. It is provided in the base of the theory of the prevention and control desertification.3. Indicators of the sustainable development assessments in the sand-desertification region have been made in this thesis. These indicators are main line in the control and prevention of the sand-desertification process. It was presented in the improvement or inhibitory factors of the sand-desertification with analysis hierarchical process method. Its top layer i e. aim is the sustainable development in the sand-desertification region. In the second, i.e. control layer these indicators of the sustainable development assessment included the sand-desertification extent, natural environmental factors, the extents of human activities and socio-economic conditions, and so on. After then next layer was described by next indicators. Total system was consisted of all these indicators.4. As mentioned above these indicators were employed in the assessment of the sustainable developments, where was a case of Naiman county, Keerqin sand-desertification region. Assessment results showed that the relationship between the sand-desertification and its impact factors has been described. It indicated that the natural environmental condition was a foundation, human activity was a disturbance factor, socio-economic condition was a force factor. At the same time the sustainable development level in the sand–desertification region of the Naiman county has been gradually increased from 1975-2000. Regional economic development in the Naiman county was corresponding with the sustainable development. Optimum management model of the sand-desertification has been recommended based on the sustainable development assessment of the Naiman county.
