Examination of a former industrial sludge basin containing organic pollutants showed that the basin had undergone substantial ecological recovery through natural forces following the removal of surface water in 1982. Conventional phases of ecological recovery (plant invasion and succession) have occurred, but the structure of the biodiverse plant community (51 species and 22 families) was different from that at a recovering non-polluted disturbed site. Three plant species (Bermuda grass, mulberry, and sunflower) believed to be early invaders of the basin still persist in large numbers indicating that these species are well suited to cope with normal environmental stresses at this area (i.e. seasonal drought and flood) as well as organic pollutants. There was an indication that early invaders of the site fostered disappearance of contaminants thereby creating more favorable conditions for a broader spectrum of plants to grow. Vegetation analyses of naturally vegetated hazardous waste sites hold promise as a screening device for identifying plant species and management practices worthy of further phytoremediation investigations.
对一个曾经含有有机污染物的工业污泥池进行检查，发现自 1982 年地表水被抽干后，该池在自然力量的作用下经历了实质性的生态恢复。生态恢复的常规阶段（植物入侵和演替）已经发生，但生物多样性植物群落的结构（51 种和 22 科）与在受污染干扰得到恢复的非污染地点的结构不同。三种被认为是该池早期入侵种的植物（百慕大草、桑树和向日葵）仍然大量存在，这表明这些物种非常适合应对该地区的正常环境压力（即季节性干旱和洪水）以及有机污染物。有迹象表明，该地点的早期入侵种促进了污染物的消失，从而为更广泛的植物生长创造了更有利的条件。对自然植被危险废物场进行植被分析有望成为一种筛选手段，以确定值得进一步进行植物修复研究的植物物种和管理实践。
