中文摘要	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87.06cm63.32cm42.13cm6.21cm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2.3321.250.33变化,Shannon-Wiener指数从2.962.311.940.42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。
英文摘要	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% to 14% 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 indicato 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.
