摘要:
 选取影响朱鹮生境适宜性的9个环境因子，基于层次分析法（AHP）构建生境适宜指数（HSI）模型，结合地理探测器，分析陕西省洋县朱鹮生境适宜性程度及主要影响因子。结果表明：1）洋县朱鹮生境适宜性整体处于中等偏高水平；2）洋县境内朱鹮生境适宜区和较适宜区空间分布连贯性较差，空间分异特征明显，呈现东、南、北高，中间和西低的格局；3）单因子中，对朱鹮生境适宜性空间分异特征解释力较强的主要因子由大到小依次为距水体距离（0.501）、距水源距离（0.359）、植被类型（0.162）、海拔（0.155）、距道路距离（0.152），其他环境因子的解释力（q）偏弱，q均未超过0.1；4）交互因子中，q（x1∩x2）为0.5以上交互作用的因子均是距水源（水体）距离叠加其他因子产生。其中，q（距水体距离∩距道路距离）为0.602，仅次于q（距水体距离∩距水源距离）最高值（0.725）。研究可为濒危动物生境保护以及栖息地管理提供理论基础和科学依据。
Abstract:
 In the 1980s,only 7 wild crested ibis (Nipponia nippon) were found in Yangxian County,Shaanxi Province,China.It is of great significance for the survival of crested ibis to evaluate the habitat suitability.In this paper,nine disturbance factors which affect the habitat suitability of crested ibis were selected,habitat suitability index (HSI) model was built based on AHP (analytic hierarchy process).Combined with geographical detectors,the habitat suitability degree and main disturbance factors of crested ibis were evaluated and analyzed.The results showed 1) The overall habitat suitability of crested ibis was at medium to high levels in Yangxian County.2) The spatial distribution coherence of suitable habitat areas and less suitable habitat areas was poor and spatial differentiation was obvious,presenting a pattern of "high in the east,south and north,low in the middle and west".3) Among the single factors,the main factors with strong explanatory power for the spatial differentiation of habitat suitability were distance from water (0.501),distance from water source (0.359),vegetation type (0.162),altitude (0.155) and distance from road (0.152).The explanatory power (q) of other disturbance factors was weak,and the q value did not exceed 0.1.4) Among the interaction factors,factors of the q(x1∩x2) value above 0.5 were generated by the distance from the water source (water body) superimposed with other factors.Among them,the value of q (distance from water body∩distance from road) was 0.602,which was the second to the highest value of q (distance from water body∩distance from water source) (0.725).Based on the research results,four suggestions and reflections on habitat protection and conservation management of crested ibis were put forward.The research can provide theoretical basis and scientific basis for habitat protection and habitat management of endangered animals.
