Abstract:

Karst rocky desertification is a kind of ecological disasters，distributed widely in mountainous karst area of Southwest China.Over the last three decades，karst rocky desertification has become more and more serious，intensely restricting the economical development and ecology quality enhancement of Southwest China.Hence we must pay more attention to it.First，the current situation of karst rocky desertification research is discussed from the following three aspects：concept，causes and treatment.And then the coexisting related questions are analyzed，including the partial of research，the lack of quantitative research，the disagreement in criteria and the scarcity of landscape ecological research.Landscape ecology has its own theoretical predominance and methodology system，and we may resolve some related questions by using landscape ecological theories and research methods.Based on that，the future four prospects on karst rocky desertification research are finally presented in terms of landscape ecology，namely landscape pattern change research，study on landscape heterogeneity and regionalization，dynamic simulation on the process of karst rocky desertification and research on biodiversity.

Key words: karst rocky desertification, causes, treatment, landscape ecology, research, prospects
