研究对象是中国河北省赤城县闫家坪村的两种共存网蛱蝶—大网蛱蝶和金堇蛱蝶,这两种网蛱蝶以不同的集合种群类型续存.在此区域内,适宜网蛱蝶生存的栖息地斑块是干草地.在这里主要的人为干扰是放牧和耕作.研究结果表明:斑块内是否嵌有耕地和在斑块内放牧对金堇蛱蝶的斑块占据性以及种群密度有交互作用,金堇蛱蝶在内部嵌有耕地并且适度放牧的斑块上的占据性和种群密度最高.斑块内是否嵌有耕地对两种网蛱蝶的斑块占据性都有显著影响,两种网蛱蝶都喜欢占据内部嵌有耕地的斑块.斑块内是否嵌有耕地对金堇蛱蝶的种群密度有显著影响,而对大网蛱蝶种群密度没有影响.但是两种网蛱蝶在田垄间的幼虫组的比例有逐年增加的趋势.两种网蛱蝶都是在适度放牧的斑块内有最高的占据性和种群密度.结果说明在该类型山区的小规模的耕种和适度放牧对蝴蝶的保育是有利的.斑块内是否嵌有耕地和在斑块内放牧对两种网蛱蝶有不同的影响.因此,在对有人为活动的山区进行保育规划时,要综合考虑其利弊以及不同物种的异同.
The study object is two coexisting nectar-butterfly nematodes and golden-banded butterfly Butterflies in Yanjiaping Village, Chicheng County, Hebei Province, China, which are found in different types of assemblages. In this region, Habitat patches of the horsetail butterfly habitat are dry grass, where the main man-made disturbances are grazing and tillage.The results show that: Plaque embedded in the plains and plaque grazing on the golden pansy butterfly plaque occupancy As well as the interaction of population density, the occupancy and population density of the golden pteridoglossus inplanting cultivated land and moderate grazing were the highest among all the cultivars in the plaque Had significant impact on the population of both landraces and butterflys.The two landra nets liked to occupy the plaques embedded with cultivated land.It was found that the cultivated land in the plaques had a significant effect on the population density of the golden butterfly but did not affect the population density of the euonymus maculata. However, the proportion of larvae of two species of moths in the ridge increased year by year, and the two species of moths had the highest occupancy and population density in the moderate grazing patches.The results showed that in the type of mountainous area Small-scale cultivation and moderate grazing The conservation of butterflies is beneficial.If the cultivated land is embedded in the plains and the grazing within the plaques has different effects on the two species of moths, therefore, when planning conservation activities in mountainous areas, we should consider the pros and cons As well as the similarities and differences of different species.
