摘要

通过对小流域不同坡面上鱼鳞坑的内外群落植被调查

研究了该地区鱼鳞坑内外植被群落特征与海拔及坡向的关系。(1)阴坡鱼鳞坑内的盖度大于阳坡鱼鳞坑内的盖度

并且达到极显著水平。(2)坡向不是控制该区域植被群落多样性的主导因子。(3)不同土地类型鱼鳞坑外的群落丰富度指数

Shannon- Wiener指数及同-土地类型的鱼鳞坑内外群落的指数均与海拔高度成极显著的抛物线函数关系

但是与鱼鳞坑内群落的多样性指数不成显著相关关系。结果显示

可以通过像鱼鳞坑这样的整地方式来改变小生境以促进群落植被的物种多样性。

Abstract

Based on vegetation communities inside and outside fish-scale pits on the different slopes of small watershed

the relationships between vegetation comm u nities inside and outside fish-scale pits and latitude as well as slope aspect are discussed.The results d rawn from this case study are as follows:(1) The coverage of t he vegetation community inside fish-scale pits on northern slope is higher than that on southern slope

reaching a very significant level.(2) Slope aspect is not the dominant factor in determining the diversity of the vegetation communities.(3) The relationships between altitude and the vegetation community richness outside fish-scale pits with different land uses

Shannon-Wiener indexes

and indexes for the vegetation communities inside and outside fish-scale pits with the same land use pattern can be described by parabolic functions

reaching a remarkably significant level.However

the relationship between altitude and diversity indexes of vegetation communities inside fish-scale pits does not reach a significant level.The results imply that community diversity can be increased by methods of changing niche

such as fish-scale pit preparation.
