摘要

在粤北石漠化地区运用面上调查、定位观测和模拟降雨试验相结合的方法,研究了石漠化地区植被退化特征及其与降雨截留量、土壤的相关性。结果表明：石漠化土地从轻度→中度→重度→极重度变化时,植物群落从草本+藤本+乔灌木→草本→苔藓变化,群落层片从4层→4层→2层→1层变化, 平均高度从87.06 cm→63.32 cm→42.13cm→6.21 cm变化,物种减少比例从0%→14%→46%→86%变化,植物优势种从黄连木+苎麻+黄荆+三裂叶野葛→黄连木+青蒿+野菊→五节芒+野古草+牛筋草→苔藓变化,Margalef丰富度指数从2.33 →2→1.25→0.33变化,Shannon-Wiener指数从2.96→2.31→1.94→0.42变化。植被退化特征与降雨和土壤理化性质都呈显著相关性。

Abstract

We studied the vegetation degradation and its correlation with rainfall interception and soil in rocky desertification area of northern Guangdong with methods of site investigation, station-oriented observation and simulated test. The results showed that: In accordance to the light, middle, severe and extremely severe rocky desertificaiton, the plant community succession was from Herb+liana+shrub+Arbor to herb to bryophyta, the community's layer was from 4 layers to 4 layers to 2 layers to 1 layer; the average height was from 87.06 cm to 63.32 cm to 42.13 cm to 6.21 cm; proportion of species reduction was from 0% to14% to 46% to 86%; the dominant species of plants were from Pistacia chinensis+Boehmeria nivea+Vitex negundo+Pueraria phaseoloides to Pistacia chinensis+Artemisia apiacea+Chrysanthemum indicum to Miscanthus floridulu+Arundinella anomala+Eleusine indica to bryophyta; the Margalef index was from 2.33 to 2 to 1.25 to 0.33; the Shannon-Wiener index was from 2.96 to 2.31 to 1.94 to 0.42. There is a significant correlation both between vegetation degradation and rainfall and between vegetation degradation and soil.

Key words： rocky desertification; vegetation degradation; rainfall; soil; northern Guangdong
