石漠化演化因素及非线性探讨———以贵州铜仁地区为例

Study on the Factors of Rocky Desertification and It’s Non line Research——A case in Tongren Prefecture Guizhou Province

石漠化是喀斯特地貌地区最大的生态问题,是在岩溶等自然因素和人类活动等人为因素的影响下不断进行着演化。从长期看,这一演化过程具有不可预测性,短期内却有细微可预见性。现如今在经济不断发展的同时,石漠化也在扩展。本文在分析引起石漠化的自然因素和人为因素的基础上,确定了自然因素中的喀斯特地貌和人为因素中的政府调控行为为演化的主导因素,初步探索了促使石漠化演化的主导因素作用所具有的非线性关系,这对石漠化治理,抑制石漠化扩展有一定的实际意义。

Rocky desertification is the biggest ecological problems in the Karst area,which is evolving through natural factors and human activities.In the long term,this evolution has not predictable,while there are minor short-term predictability.Nowadays,the economy is growing,at the same time,rocky desertification is also expanding.Based on the analysis of rocky desertification caused by natural factors and human factors。The Karst topography and the regulation behavior of the government are the dominant factors for the evolution of rocky desertification,an initial explored the factor promoting the evolution of rocky desertification has the role of non-linear relationship,which have some practical significance.in controlling and inhibiting the expansion of rocky desertification.
