摘　　要：将森林植物耐污能力划分出4个等级,并依此对闽南地区8个排污1~11 a的养猪场蓄污池、排污沟周边植被进行调查,初步筛选出Ⅰ级耐污植物10种,其中木本1种;Ⅱ级耐污植物有29种,其中木本18种;Ⅲ级耐污植物15种,其中木本5种;Ⅳ级耐污植物1种,其中木本1种。调查结果为闽南地区利用森林生态系统治理养殖污水、试行林畜复合经营提供了参考。本文还简述了森林生态系统具有根系庞大、生长量高、生长周期长、结构复杂、能自行演替、可以更多更长时间更稳定吸收养猪污染物的特点,提出在选择生态治污树种时应首选速生树种、常绿树种、阔叶树种的观点。In order to screen out the plant species can tolerate wastewater, vegetation in and around cesspits that have stored wastewater for periods ranging from 1 to 11 years was investigated in southern Fujian. Vegetation was assessed for its ability to tolerate wastewater on a 4 point scale. This assessment identified： 10 first-grade species （containing 1 woody plant species）; 29 second-grade species （containing 18 woody plant species）; 15 third-grade species （containing 5 woody plant species）; and, just 1 fourth-grade species which itself was a woody plant species. This research can provide guidance for disposing of sewage waters using forestry ecosystems and realizing multiple-use management of forests in southern Fujian. Compared with crop or hydrophyte ecosystems, forests have markedly greater root systems, biomass and life cycles whilst also having potential to be self-perpetuating. On account of these characteristics, forest ecosystems can absorb/treat more wastewater and over longer time periods, suggesting that fast-growing, evergreen, broadleaf species could be the best choice for uptake and utilization of wastewater.
