Karst rocky desertification is a geo-ecological problem in Southwest China because of nature and man-made factors, which restricts the development of local economic and social. Soil and water erosion is one of the most harmful form of rocky desertification, but the management methods still keep in the exploratory stage. Biological soil crust is the organic complexes of biotic components includi...

Over the past several thousand years, arid and semiarid China has experienced a series of asynchronous desertification events in its semiarid sandy and desert regions, but the precise identification of the driving forces of such events has remained elusive. In this paper we identify two rapid desertification events (RDEs) at ~4.6 ± 0.2 ka BP and ~3.3 ± 0.2 ka BP from the JJ Profile, located in ...

Introduction Trend of increasing natural resource degradation in many parts of the world, is a serious threat to humanity. Desertification is one of the manifestations of the damage that has already suffered as a scourge of many countries, including developing countries are. At present, remote sensing is one of technologies with timeliness data and accuracy suitable for monitoring land use c...

Land desertification has become a significant issue of economy and ecological environment in global area. In this paper, we have applied the object-oriented method to the research of Zhenglanqi basin and the West of Badain Jaran Desert which present obviously different characters of china. On the basis of the multi-spectral images of Beijing-1 in June and September in 2006, under the standard c...

The slippery slope framework (SSF) of tax compliance postulates that taxpayers’ behaviour depends on the two dimensions: trust in authorities and power authorities. In an attempt to overcome common-method biases, present study tests main assumptions SSF with a sample 44 countries/regions. Country/region-level indices are calculated based experimental data involving 14,509 participants related s...

Desertification is a global environmental problem, and arid dunes with sparse vegetation are especially vulnerable to desertification. One way to combat desertification is to increase vegetation cover by planting plant species that can realize fast population expansion, even in harsh environments. To evaluate the success of planted species and provide guidance for selecting proper species to st...
