Vegetation recovery and poverty alleviation are critical problems in the karst national designed poor counties (NPDC) in southwest China. However, little information is available about the relationship between poverty and vegetation dynamics in these areas. In this study, we used remote sensing and statistical datasets from 2000 to 2015 to identify the

Pattern simulation of karst rocky desertification based on cellular automata
Acta Ecologica Sinica, 2012Desertification in the karst mountain regions of southwest China is one of the most challenging environmental issues in western China because of its severe negative effects on the local community.Based on natural and cultural factors that cause rocky desertification occurrence and development,a simple,effective simulation and prediction model for karst

Comprehensive assessment of rocky desertification treatment in Southwest China karst
Land Degradation and DevelopmentAbstractRocky desertification is a prominent ecological issue in Southwest China's karst region, ranking among the nation's three primary ecological challenges alongside soil erosion and desertification. The government initiated the Rocky Desertification Treatment Program in 2008, lacking a comprehensive evaluation of its benefits. This study evaluates

Causes and Prevention Measures of Rocky Desertification in Bijie, China
Vegetos- An International Journal of Plant Research, 2014Bijie is located in the northwest of Guizhou Province in western China. Biejie Experimental Area was founded by Hu Jintao, the former secretary of Guizhou provincial Party committee in as a prelude to Western Development. Bijie city has a large population but is backward in economy, which mainly caused by serious rocky desertification.

Spectral indices for estimating ecological indicators of karst rocky desertification
International Journal of Remote Sensing, 2010Karst rocky desertification is a process of land desertification associated with human disturbance of the fragile eco-geological setting of karst ecosystems. The fractional cover of photosynthetic vegetation (PV), non-photosynthetic vegetation (NPV), bare soil and exposed bedrock are key ecological indicators of the extent and degree of land ...

Mapping karst rocky desertification using Landsat 8 images
Remote Sensing Letters, 2015Karst rocky desertification (KRD) is a serious ecological problem in southwest China. Various remote sensing techniques are available for investigating KRD. Landsat 8 Operational Land Imager (OLI) data, acquired in September (summer) 2013 and January (winter) 2014, were used to analyse the role of vegetation fraction, bedrock exposure, and slope on KRD

[Theoretical model for rocky desertification control in karst area].
Ying yong sheng tai xue bao = The journal of applied ecology, 2008Based on the basic principles of restoration ecology, the trigger-action model for rocky desertification control was proposed, i. e. , the ability that an ecosystem enables itself to develop was called dominant force, and the interfering factor resulting in the deviation of the climax of ecological succession from its preconcerted status was called ...

Developing new spectral indices for karst rocky desertification monitoring in Southwest China
2009 IEEE International Geoscience and Remote Sensing Symposium, 2009Karst rocky desertification is a special kind of land desertification developed under violent human impacts on the vulnerable eco-geo-environment of karst ecosystem. The fractional cover of photosynthetic vegetation (PV), non-photosynthetic vegetation (NPV), bare soil and exposed bedrock are key indicators of the extent and degree of land degradation ...

Karst rocky desertification in southwestern China: geomorphology, landuse, impact and rehabilitation
Land Degradation & Development, 2004AbstractKarst rocky desertification is a process of land degradation involving serious soil erosion, extensive exposure of basement rocks, drastic decrease in soil productivity, and the appearance of a desert‐like landscape. It is caused by irrational, intensive land use on a fragile karst geo‐ecological environment.
