Unexploited land change is a main driver of regional eco-environment change. Through an integrated technique of geographic information system (GIS), remote sensing (RS), and global positioning system (GPS), the authors attempted to address this topic by examining unexploited land conversion in Guiyang City in Guizhou province in southwestern China as a case study, as well as looking at the effect of policies in land use from 1996 to 2010 in the same area. Results showed that: Agricultural development of unexploited land was encouraged from 1996 to 2000, and a progression conversion process with direct and indirect transformations overlaid was formed by unexploited land → arable land + unexploited land → forest land and grass land → arable land. The conversion management of unexploited land was enhanced, unexploited land occupied for construction was controlled, and the area of unexploited land converted to forest land and grassland showed an upward trend from 2000 to 2006. Local government was encouraged and supported in exploring construction and use of unexploited land, and achieved the maximum value by converting unexploited land to construction land, as a result we see the area of forest land and grassland decreased from 2006 to 2010.Keywords

Livestock pollution is the main source of environmental pollution in rural areas. To explore the effects of the farmers’ environmental behaviour on livestock pollution using the questionnaire and interview methods, the environmental cognition of farmers and their willingness to practice faeces decontamination in livestock breeding were analysed with survey data collected from 80 farmers in Xiantao of China, on September 2016. Results show that the environmental cognition of farmers is related to the status of rural development. In addition, when the farmers’ educational level is high, the environmental cognition is also high. The farmers’ environmental behaviour is also influenced by their state of environmental cognition and willingness to practice faeces decontamination. Production scale and government policies are also important factors affecting the behaviours of farmers. The choice of faeces decontamination has a positive interrelated relationship with the education levels of farmers, as well as the livestock breeding scale and time. This study’s findings provide guidelines on the formulation of relevant policies to control pollution resulting from livestock farming.Keywords

Soil and water losses have become a serious ecological and environmental problems, and how to scientifically carry out soil and water losses risk assessment on soil erosion prevention and treatment of macroeconomic decisionmaking are very important. Based on the concept of cloud matter element, the associated function and cloud model were used to calculate the association value, then an improved matter-element model of extension cloud combination was established, at last, the evaluation model was introduced into soil and water losses risk assessment. Through the project case in a coal mine shows that the improved evaluation model can get a reasonable risk evaluation result. In practical application, the evaluation result of the extension cloud combination model constructed by classical extension correlation function is closer to the visual statistical value.Keywords
Fextenics, cloud model, cloud matter element, a coal mine, soil and water losses evaluation.
