摘要

通过对滇东南西畴县石漠化山地4种不同土类的理化性质进行定点观测和地力变化的分析，结果表明：黑色石灰土的肥力较佳，其次是红色石灰土，这是由于黑色石灰土多年来进行封山育林，红色石灰土进行了平衡施肥；3年后黄色石灰土的理化性质有很大改善，土壤肥力有很大提高，这是退耕还林的结果；说明退耕还林、封山育林和耕地的平衡施肥有利于石漠化山地土壤肥力的改善。

Abstract

A study on the physicochemical property of four karst mountains desertification soils in Xichong county of southeastern Yunnan was conducted by ocean weather station observation. The results showed that the land capacity of rendzina is the highest and the land capacity of terra rossa is higher

which resulted by closing hillsides to facilitate afforestation for many years of rendzina

and balance fertilizing of terra rossa. As returning land for farming to forestry

the physicochemical property and land capacity of brown rendzina has been greatly improved after three years. Closing hillsides to facilitate afforestation

returning land for farming to forestry and balance fertilizing are three good land capacity improvement approaches in karst mountains desertification soil of southeastern Yunnan.
