The results showed that the critical values of Cd,Pb,and Cu in the Juncus Effuses grown soil were set at 10,100 and 100mg kg-1 respectively,but Juncus Effuses was not able to grow in the Zn polluted soil.
结果表明：种植灯心草土壤中的Cd、Pb、Cu三种重金属临界值可分别设定为10mg kg-1、100 mg kg-1、100mg kg-1。灯心草不适合在Zn污染的土壤中种植，土壤中As临界值尚需作进一步的研究来确定。

Results showed that biomass of the ground part of Juncus Effuses was inhabited to a certain degree. When the dosages of the heavy metals added to the soils were close to Grade II Criteria of the State Soil Environmental Quality Standard (GB15618-95), Juncus Effuses could still grow normally in appearance though its yield decreased by 10%, however biomass of the underground part was not much affected.

Based on plant morphological traits, some types of strategies could be divided. The regeneration strategies of three species, Eriocaulon buergerianum, Juncus articulatus and Sagittaria potamogetifolia, had characteristics of r-strategists, and Oryza rufipogon, Scirpus triangulatus and Eleocharis plantagineiformis had characteristics of K-strategists.
根据植物的功能形态学特征，可以分出一些生活史对策类型，如从种子特征来看，谷精草、小花灯心草和小慈姑等植物的更新对策具有明显的r-对策特点，粉被苔草、野荸荠和普通野生稻等具有一定的K-对策特点；依据成株特征也可以区分出竞争、躲避或耐压对策的定居对策类型。
