人工施肥对韶峰景观竹林中昆虫多样性的影响

     

摘要

The forests of Phyllostachys heterocycla cv. Pubescens vrete fertilized with nitrogenous fertilizer, kalium fertilizer, phosphor fertilizer and multiple fertilizers. The results show that the insect community in the forests were changed The kinds of insect, numbers of insect and the percent of vegetable insect increased after treated with nitrogenous and multiple fertilizer, the kind and percent of other insects decreased, the index of H increased, while the index of G decreased. The differences of stability and complex did not change obviously. The changes of insect community were not obvious in the sample feritilized with kalium fertilizer and phosphor fertilizer. The results show that the fertilizer could change the composition of insect community, but the stability did not change markedly.%对韶山景观竹林中施以氮、磷、钾和复合肥,于处理前、处理后3个月、6个月和15个月后调查了样中的昆虫群落.结果表明,人工施肥处理后引起毛竹林中昆虫群落发生变化,施氮肥和复合肥促进了昆虫物种数和个体数的增加;引起了植食昆虫比例的增加,相对来说,其它昆虫和寄生昆虫的比例减少;H指数增加较高;G指数下降较多;但是其稳定性和复杂程度差异变化不大.施钾和磷把样地的变化不是很明显.结果表明,人工施肥虽然在一定时间内能影响昆虫群落的组成,但对其稳定性影响不大.
