试论江西地质环境与林地的地域分异关系

ON THE RELATIONSHIP BETWEEN GEOLOGICAL ENVIRONMENT AND GEOGRAPHICAL VARIATION OF FOREST LAND IN JIANGXI

在一定的生物气候条件下,地质环境制约着地貌形态的发育,影响着地区气候,水文条件的变化;土壤的发育及其地域分布,制约着植被的分布和林木的生长,是林地地域分异的重要因子。地质环境条件长期、稳定地对林木生长起作用,研究它与林地地域分异的关系对合理组织森林经营与利用,无疑是一项十分重要的基础工作.

Under given conditions of bioclimate the geological environment has influence on geomorphic development and the changes of hydrologic and climatic factors and the devel- opment and distribution of soil restrict vegetation distribution and tree growth.So the geo- logical environment is a major factor that makes forest land vary geographically and acts steadily on tree growth over a long period of time.The study on the effect of the geological environment on geographical variation of forest land is very important in planning rational management and exploitation of forest.
