【摘要】：依托實(shí)際邊坡生態(tài)防護(hù)工程,采用定位動態(tài)研究法,對黔中3個不同坡向、坡度的石質(zhì)邊坡在人工植被建植后3年內(nèi)物種組成每月進(jìn)行跟蹤調(diào)查,以期揭示邊坡生態(tài)防護(hù)工程植被建植后,人工植物群落演替初期基本特征,為工程石質(zhì)邊坡植被重建及后期養(yǎng)護(hù)管理提供科學(xué)的理論基礎(chǔ)。結(jié)果表明:(1)在觀察期內(nèi),樣地中共出現(xiàn)了51種植物,分屬13科43屬,主要為禾本科、豆科和菊科植物;(2)建植后第1年內(nèi)物種主要以初播物種為主,群落為黑麥草群落;第2、3年內(nèi),隨著當(dāng)?shù)刂参锏娜肭?物種數(shù)大量增加,群落優(yōu)勢種發(fā)生變化,1號坡群落逐漸發(fā)展為黑麥草+野菊+馬棘群落,2號坡逐漸發(fā)展為黑麥草+馬棘+刺槐群落,3號坡發(fā)展為黑麥草+千里光+刺槐群落。群落3大功能類群分布有所變化,禾本科植物比例下降,豆科植物比例上升;(3)邊坡人工植被建植后3年內(nèi),植被群落豐富度指數(shù)、Shannon-Wiener多樣性指數(shù)、Pielou均勻度指數(shù)呈直線上升。
[Abstract]:Based on the actual slope ecological protection project, the species composition of the stone slope with three different slope directions and slopes in the middle of Guizhou was investigated monthly within 3 years after the artificial vegetation was established by using the method of dynamic location research. The purpose of this study is to reveal the basic characteristics of artificial plant community in the early stage of vegetation succession in slope ecological protection engineering, and to provide a scientific theoretical basis for vegetation reconstruction and later maintenance management of stone slope. The results showed that there were 51 species of plants, belonging to 13 families and 43 genera, in the observation period. The main species were Gramineae. The species of Leguminosae and Compositae were mainly first seeded species and the community was ryegrass community within 1 year after establishment. In the second and third years, with the invasion of local plants, the number of species increased greatly. The community dominant species changed. Slope 1 community gradually developed into ryegrass wild chrysanthemum ryegrass community, slope 2 gradually developed into ryegrass ryethorax pseudoacacia community, slope 3 developed ryegrass Qianliguang Robinia pseudoacacia community. The distribution of the three major functional groups of the community changed, the proportion of Gramineae decreased, and the proportion of legumes increased. Within 3 years after the establishment of artificial slope vegetation, Shannon-Wiener diversity index and Pielou evenness index increased linearly.
