| 摘 要： | 采用不同灌溉量（每周0、300 m3· hm-2、600 m3· hm-2、900 m3· hm-2、1200 m3· hm-2、1500 m3· hm-2）的生活污水对杨树林地进行灌溉试验，分析了生活污水灌溉杨树林地对其林下植物多样性及其生物量的影响。结果表明，随着灌溉量的增加，林下植物总物种数、多样性指数、生态优势度指数、均匀度指数增加，在每周灌溉600 m3· hm-2时达到最大值，然后随着灌溉量的增加而降低。林下植物的地下生物量也随着灌溉量的增加而增加，但在每周灌溉1200 m3· hm-2时达到最大值后开始降低。

| Abstract: | A wastewater irrigation experiment with different irrigation volume （0, 300 m3 · hm-2 , 600 m3 · hm-2 , 900 m3 · hm-2 , 1 200 m3 · hm -2 and 1 500 m3 · hm-2 per week） was conducted to study the effects of domestic wastewater on undergrowth plant of poplar plantation .The results showed that total species number , diversity in-dex , predominance index and evenness index of undergrowth plant all increased with the increment of irrigation volume firstly, reached a maximum at the irrigation volume 600 m3 · hm -2 per week and then decreased .The un-derground biomass of undergrowth plant also increased with the increment of irrigation volume with the maximum at 1 200 m3 · hm -2 per week and then decreased . |
