“Qinglong Pattern” Creates Another “Get-Rich on Rocky Desertification” Miracle
2021Qinglong County, mainly composed of plateau and canyon, is home to high mountains, steep slopes and deep valleys. Karst is developed intensely in this area. Qinglong is of typical karst landscape with an altitude ranging from 543 to 2,025 m. It is one of the largest areas with intense karst, complex and diverse large-area rocky desertification in ...

Karst rocky desertification information extraction with EO-1 Hyperion data
SPIE Proceedings, 2008Karst rocky desertification is a special kind of land desertification developed under violent human impacts on the vulnerable eco-geo-environment of karst ecosystem. The process of karst rocky desertification results in simultaneous and complex variations of many interrelated soil, rock and vegetation biogeophysical parameters, rendering it difficult

Phenology-tuned karst rocky desertification monitoring using satellite image time series
2014 Third International Workshop on Earth Observation and Remote Sensing Applications (EORSA), 2014Remote sensing has been used in karst studies. The aim of this work is to investigate the use of MODIS time series to monitor and estimate karst rocky desertification (KRD). We propose a new phenology-tuned KRD model based BFAST (Breaks For Additive Seasonal and Trend) approach, Our strategy for KRD monitoring involving several steps: (a) phenology ...

Estimate ecological indicators of karst rocky desertification by spectral unmixing algorithm
SPIE Proceedings, 2013Coverage rates of vegetation and exposed bedrock are two key indicators of karst rocky desertification (KRD) environments. Based on spectral unmixing algorithm, abundance of vegetation and exposed rock were retrieved from the hyperspectral Hyperion image.

[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 ...

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.

Implication of different humic acid fractions in soils under karst rocky desertification
CATENA, 2019Abstract Karst rocky desertification, a kind of intense soil degradation, has become an urgent environmental issue in the karst region of southwest China. It was found that limestone soil, a typical soil of the karst region, is more vulnerable to karst rocky desertification than adjacent other soils although limestone soil has relatively high TOC ...

Multi‐Scale Anthropogenic Driving Forces of Karst Rocky Desertification in Southwest China
Land Degradation & Development, 2013AbstractKarst rocky desertification (KRD) is a type of land degradation especially prominent in southwest China. This article analyzes the anthropogenic driving forces of KRD at two scales: rural locality and its macro socio‐economic circumstances. At the rural locality scale, the intensive human pressure on land because of a large and fast growing ...
