摘要
滇西北的怒江、迪庆两州地处云南省高寒高山峡谷区,地形破碎而陡峻,耕地稀缺,陡坡种植业占有很高的比重。由于人口的增长,陡坡耕地仍将作为该地区的主要耕地长期存在。这种传统的耕种方式已对环境产生了深刻的负效应。本文根据其生存条件和利用现状就通过改良以取得持续利用的方向和途径作了初步探讨。
The areas Nujiang and Diqing,those are special areas with high mountains and deep valleys.The topographys here are broken and steep , and cultivated lands is scarce.The plant enterprise occupys an important position in local economic system, which closely relates with the special geographic environment. Because of the rapid incrsase of population, the plant enterprise on steepslope land has quickly developed and the local environment is harmfully affected by the cultivated action. Considering the realty of these steep - slope cultivated land in these areas. and fitting the purpose of soil we give some consideration and method here.
