不同营林面积情景下鹿科动物的潜在生境分布
Potential habitat distribution for Cervids based on different forest management area scenarios
摘要
Abstract
It is theoretically and practically important to explore suitable habitat distribution of the Cervids for relieving the confliction between small-scale human management and large-scale habitat conservation in a human-disturbed forest landscape.Using the present locations of Cervids (n =196) observed in field investigations in 2013,2014 and 2015,we grouped 17 environmental predictor variables into four predictor classes (terrain,habitat type,vegetation feature,and interference) and used those variables to build a maximum entropy (MaxEnt) model.Then,we estimated the potential habitat of red deer and roe deer,and determined the contribution of environmental factors to the distribution characteristics in four forest management area scenarios by this model.Results showed that models validation had high average accuracy and the stability appeared satisfactory.The potential suitable habitat for Cervids was located mostly in the eastern region.The environmental factors significantly affecting habitat suitability of red deer and roe deer were similar in different scenarios,and they were distance to farmland,distance to settlement,distance to river,distance to management area and elevation.Distance to management area factor was found to have a certain extent effect on habitat suitability with contribution probability from 4％ to 6％.The distance to management area was about 1200-1300 m both for red deer and roe deer.In none management scenario,the suitable habitat was widely distributed in large area.With the increase of management area,the suitable habitat decreased.When the management area expanded to the twofold or threefold of the current one,Cervids habitat shrank greatly.关键词
