摘要
采用“最近异境法”和“主观取样法”对河北省围场县黑琴鸡的觅食、炫耀、栖息和营巢生境分别进行了调查分析,得出了黑琴鸡对生境的选择性为:(1)分布在海拔1100~1200m以上的坝上地区;(2)距居民点较远;(3)在比较开敞的地带,同时附近具有比较高大的森林;(4)地势有起伏,但不大,坡度以5~30°为多;(5)喜欢像华北落叶松林那样,林冠郁闭,林下开阔,食物丰富的环境。
By using the methods of “Nearest different environments” and “Subjective samplings”,we have made an investigation on the feeding,displaying,resting and nest building habitat of Black Grouse in Weichang County,Hebei Province. The habitats selected by Black Grouse are likely to be: (1) distributed over the highland of 1100~1200 meters above sea level; (2) relatively remote from residential areas; (3) open land belts usually with big tree forests nearby; (4) rolling terrains with a slope of 5~30°; (5) environments in which forest like North China larch with dense forests and with an open ground under trees and rich in food resources.
