Using nuclear DNA C-values for 539 angiosperms in China, we examined the variation of these values among growth forms and taxonomic groups and the relationship of these values with invasiveness. Mean DNA C-value of the 539 angiosperm species was 4.06 pg. Mean DNA C-value was(1) significantly lower for woody species (1.84 pg) than for herbaceous species(5.02 pg);(2) significantly lower for 360 dicots (2.20 pg) than for 179 monocots (7.80 pg);(3) significantly lower for annuals (2.78 pg) than for perennials(6.65 pg);(4) significantly lower for 134 weed species (1.93 pg) than for herbaceous non-weeds (6.75 pg) and for several families that have an unusually high proportion of weed species;(5) significantly lower for 47 exotic weed species (1.76 pg) than for 134 native weeds (1.93 pg), but significantly lower than that of "non-weedy" herbaceous species (6.75 pg);(6) lower for weeds than for "non-weedy" species in same genus or family; and (7) in herbaceous species, generally lower for weedy compared to "non-weedy" species, with some exceptions such as Avena fatua, whose DNA C-value is as high as 14.15 pg, contrarily, and some "non-weedy" herbaceous species in Cruciferae and Cucurbitaceae with very low values.

Species richness and Pielou evenness index were used to measure species diversity. Species richness in polluted area was 32-67, while in control area it was 47-82. Pielou evenness index of tree layer was 0.1161-0.8509, while those of shrub layer and herb layer were 0.1763-0.3249 and 0.0443-0.2601, respectively. The results showed that both species richness and Pielou evenness index were influenced by the point source pollution. Species importance values showed significant differences between polluted area and control area. Dominance of different species had changed, and some species even disappeared under the pressure of pollution, indicating a process of species replacement in plant communities. Such species replacement can provide a scientific basis for species selection for restoration of human-damaged ecosystem. The natural regeneration of Quercus variabilis was insensitive to pollution, while Cupressus funebris was effected seriously.

仅在污染区中出现的物种数量远低于仅在对照区中出现的物种数量；(2)可分出4种基本的群落类型：马尾松林、柏木林、栓皮栎林和马尾松＋栓皮栎林，各群落特定层次的物种丰富度指数以及Pielou均匀度指数在污染区与对照区之间存在显著差异；(3)污染胁迫下，物种在群落中的生态优势度发生了变化，反映了群落中不同物种相互替代的过程，这种物种的替代可为今后受损生态系统人为恢复过程中物种的筛选提供一定的理论参考；(4)对群落中王要物种更新的调查发现：栓皮栎林对污染不敏感；柏木林污染区与对照区幼苗数量及分布格局均有明显差异，污染条件下群落未来演替受到严重干扰。
