[Theoretical model for rocky desertification control in karst area].

Ying yong sheng tai xue bao = The journal of applied ecology, 2008
Based 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 ...

Mapping karst rocky desertification using Landsat 8 images

Remote Sensing Letters, 2015
Karst 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

Growth and changes of endogenous hormones of mulberry roots in a simulated rocky desertification area

Environmental Science and Pollution Research, 2016
We studied the growth of roots of white mulberry (Morus alba) trees in response to different water and nutrient conditions in sets of three or five containers connected via small pipes and arranged so as to simulate the heterogeneous soil conditions associated with rocky desertification.

Developing new spectral indices for karst rocky desertification monitoring in Southwest China

2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
Karst 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, 2004
Abstract Karst 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.
