desertification, rapidly increasing in area, directly threatens over 250 million people and a third of the earth’s land surface. Although it is well known that desertification could be reversed in most cases if the intensity of land use were reduced, there have been no studies of how this might be achieved on a large scale. This investigation conducted in Hunshandak Sandland of North China, explored how creation of a nature reserve might aid restoration of a degraded ecosystem. Experimental data indicate that desertification regions, if designated as a nature reserve, composed of three zone types: a core zone, a buffer zone and a transition zone, could help severely degraded ecosystems be restored with conservation of biodiversity. The buffer zones in moderately desertifiied lands could serve as a base for forage production and/or ecotourism industry. The construction of of eco-logically designed towns (eco-towns) in transition zones could accommodate migrants moved from core zones so as to develop stock production, related industry and ecotourism, This could achieve both economic and environmental sustainable development. Up to now, 5778 local inhabitants in the core zones have been moved out the severe degraded areas with the financial assistance of the central government and moved into three eco-towns of Zhenlan Banner in the Hunshadak Sandlands With the objective of greatly enhancing the economic status of the relocated persons whilst restoring the degraded sandlands.

Effects of desertification Control Project Based on Windbreak System in Daxing County, Beijing

Forestry Studies in China 2001年第2期3卷 54-59页

作者：方天纵赵廷宁王俊忠武健伟高志海北京林业大学资源与环境学院北京100083 国家林业局沙漠化防治管理中心北京100714

Windbreak system consisting of the forms of net, belt, sheet and point, has improved local eco environment greatly and promoted the level of social economy and local people's living. The result of environment impact assessment shows that the quality of eco environment has been improved obviously and the impact process is mainly positive after building of windbreak system in Daxing County of Beijing, a dry sub humid region. Effects of windbreak system and their environmental impacts are analyzed scientifically and reasonably in this paper. The study will enrich the theory of environment impact assessment and extend the scope of research, and will provide experience for the construction of windbreak system in the region.

Extraction of desertification Information in Hulun Buir Based on MODIS Image Data

[Objective] To extract desertification information of Hulun Buir region based on MODIS image data. [Method] Based on MODIS image data with the spatial res- olution of 1 km, 5 indicators which could reflect different desertification features were selected to conduct inversion. The desertification information of Hulun Buir region was extracted by decision tree classification. [Result] The desertification area of Hu- lun Buir region is 33 862 km2, accounting for 24% of the total area, and it is mainly dominated by sandiness desertification. Though field verification and mining point validation of high-resolution interpretation data, the overall accuracy of this evaluation is above 89%. [Conclusion] Evaluation method used in this study is not only effectively for large scale regional desertification monitoring but also has a better evaluation performance.

[Objective] The research aimed to study change law of phosphorus content of soil in karst rocky desertification region(KRD) during eco-restoration process such as Northwest Guangxi Province.[Method] The soil samples were collected from typical KRD in Pingguo County and Yizhou *** determining quotas of different soil samples such as soil total phosphorus content and available phosphorus content were detected,in addition the soil total phosphorus content,available phosphorus content, urease activity, catalase activity and organic matter content in different soil samples were analyzed comparatively.[Result] Aspect,vegetation type and recovery time generated obviously influences on phosphorus contents in different soil *** concrete influence order was listed as follow: phosphorus content in soil of south slope was higher than that in soil of north slope;phosphorus content in soil where Zenia insignis Chun was planted was higher than that in soil of closed forest and that of soil where Dendrocalamus minor Var. amoen was planted,additionally,phosphorus increased with recovery time. Urease activity could be used as a monitoring index of soil fertility because it is related to the change of phosphorus content.[Conclusion] The soil of karst rocky desertification region in Northwest Guangxi Province could be recovered gradually if excessive human disturbance was *** proper natural method of recovery promoted by human was taken,the recovery would reach a better result.

Reversing desertification

ChinAfrica 2019年第6期11卷 2-2页

Deserts usually impress people with the image of vast desolated sand area with no water or plants. But in China, it is no longer the case, as some parts of its vast deserts have become grassland, forest and even wetland. In the Kubuqi Desert in north China's Inner Mongolia Autonomous Region, and the Babusha Desert and Mu Us Desert in northwest China's Gansu and Shaanxi provinces, just to name a few, efforts in different forms have been made to stop the deserts from expanding, and reclaim the land from the deserts, involving people from all walks of life, such as individuals, businesses and social organizations.
