According to the experience accumulated in the preliminary poverty alleviation work of Qiandongnan Miao and Dong Autonomous Prefecture,this article summaries the main contents of Qiandongnan Prefecture’s poverty alleviation work from the aspects of key point( rural industries),assisting forces( ethnic culture and folklore industry) and important guarantee( human resources),and proposes that the rural revitalization strategy can be implemented in ethnic minority areas through consolidating the fundamental role of industrial revitalization in rural revitalization,promoting the prosperity of rural culture to realize simultaneous revitalization of rural industries and rural culture,promoting the revitalization of rural talents,and stimulating the vitality of rural areas.展开更多

The control of rocky desertification has therefore become a major concern of both the Chinese government and local populations living in karst areas. In this paper, we used the national evaluation system for monitoring rocky desertification, and adjusted relevant indices. For example, we improved the system＇s base rock exposure index with Normalized Difference Rock index（NDRI）, substituted a soil erosion index for soil depth, and from these obtained the categories and spatial distribution of rocky desertification. We also studied the main factors and functional mechanisms of rocky desertification with consideration given to natural geographic conditions such as soil, physiognomy, elevation, slope and river network density, and, also human interference factors such as population density, GDP, population distribution, and from these got spatial distribution characteristics and influencing factors of rocky desertification in Qiandongnan prefecture. Results indicate that the primary soil types of rocky desertification in the research areas include yellow, limestone and paddy soils. These rocky desertification areas are more likely to contain limestone soil than purple soil, and least likely to contain paddy soil. The distribution of moderate or severe rocky desertification in areas with moderate to steep slope is 40%, where sloping agricultural land comprises a large proportion of the total. Rocky desertification is widely distributed in regions with precipitation between 1000–1200 mm, and this precipitation is the main factor causing greater soil erosion in limestone soil base and sloping agricultural areas. Moreover, desertification is closely related to the distribution of residential areas, population density, poverty and sloping agricultural land展开更多
