Land use classification based on decision tree in karst rocky desertification areas

2011 International Conference on Electric Technology and Civil Engineering (ICETCE), 2011
Karst rocky desertification is a process of land degradation. The spatial data of desertification areas' land use is mainly through the interpretation of satellite images to get. Supervised classification and unsupervised classification are traditional interpretation methods, but their classification precision are low. And the result of desertification

Object‐Based Mapping of Karst Rocky Desertification using a Support Vector Machine

Land Degradation & Development, 2012
AbstractAccurate and cost‐effective mapping of karst rocky desertification (KRD) is still a challenge at the regional and national scale. Visual interpretation has been utilised in the majority of studies, while an automated method based on pixel data has been investigated repeatedly.

Effect of Rocky Desertification Control on the Nonlinear Trends of Gross Primary Productivity in Southwest Karst Areas, China

Land Degradation & Development
Monitoring trends in gross primary productivity (GPP) is essential for assessing changes in carbon sinks. The implementation of rocky desertification control in karst areas has led to an increase in GPP.

Effects of rocky desertification habitat on main secondary metabolites of Akebia trifoliata

In recent years, Akebia trifoliata used to restore rocky desertification environment. We first discovered that the medicinal content of A. trifoliata will increase in rocky desertification habitats, but its mechanism of action is not clear. In this study, A.
