Assessment of Land-Use and Land-Cover Change in Guangxi, China.

摘要: It is increasingly acknowledged that land-use and land-cover change has become a key subject urgently needs to be addressed in the study of global environmental change. In present study, supported by long-time-series data from 1990, 2000, 2017, we used transition matrix, Markov chain model Moran's I derive detailed information spatial patterns temporal variation change; additionally, highlight deforestation/afforestation conversion process during period 1990-2017. The results show total 4708 km2 (i.e., 2.0% area) changed Guangxi 1990 while 418 woodland been lost this region. (deforestation) gained (afforestation) were collocated with intensive forest practices past 27 years. conversions cropland grassland dominant processes deforestation afforestation, respectively. Steep slope was one major afforestation after 2000. This result mainly explained implementation "Grain for Green Program" policy large-scale development eucalyptus plantations. Further efforts should made control area. These findings can also as reference formulation sustainable management policies.
