根据岩溶地区常见不同岩溶生态景观类型,对云南省弥勒县白龙洞地区石漠化、草地、灌丛和林地4个采样区按0~10,11~20,21~30,31~40 cm等4个土层,共采集到土壤动物6 284头,分属3门8纲26类.结果显示,土壤动物主要分布在0~20 cm土层,蜱螨、弹尾和线虫是岩溶地区的优势种群.岩溶地区生态恢复过程中,常见种群和稀有种群逐渐增加,优势种群较为稳定,初期(石漠化恢复到草地)土壤动物的种群数大量增加,中期(草地恢复到灌丛)个体数量明显增加,后期(灌丛恢复到林地)种群和个体数增加缓慢,其密度可作为指示岩溶地区生态恢复的生物指标.
According to regular types of the ecological landscapes in karst area, four sampling areas, were established in Mile Bailongdong area in Yunnan Province: The rock desert area; grass area; bushwood area and forest area. With 4 stratifications( 0 - 10, 11 - 20, 21 - 30, 31 - 40 cm ) respectively. This investigation collected 6 284 species of soil animals were collected, which fell into the category of 26 kinds, 8 classes and 3 hilus. Acarian, ball tail and nemathelminth were dominant species. In the process of ecological restoration, the population of common species and tate specise increased, the population of superior species kept stable comparatively; at initial stage (the rock desert the grassplot) soil animal's species increased, at medium term (the grassplot bushwood) the quantity of various animals increased obviously, at later stage (bushwood forest land) both the population and the individual's number increased slowly, whose density couls be the biological index of ecological restoration in karst area. It could be concluded that vegetation conservation was an ecological defense in which there were various and abundant soil animals.
