Researchers and managers pay great interest in the combined use of Geographic Information System(GIS)and Multi\|variable analysis.In this research,ring\|necked pheasants' nesting habitat was modelled based on Mahalanobis distance by using GIS.In 1997 and 1998,fifty\|one nests of wild ring\|necked pheasants were discovered and orientated in Gansu,China.Distances from nests to 14 habitats'edges,measured by GIS,were used as habitat characteristic variables.Terrain factors of elevation,slope and aspect were calculated basing on digital elevation model.We generated raster layer of every variable,and calculated Mahalanobis distance value for all the grids by using GIS.The result shows that the areas,which are similar to the known used areas at the significance level of 0.95,cover only 0.68% of the whole region.On the other hand,the dissimilar areas( P <0.05) occupy 79.08% of the total area.There are many differences of habitat composition and terrain characteristics between nesting areas and non\|nesting areas.Farmland and Grass Mountain Slope occupy very large proportion in the nesting habitat.Compared with non\|nesting habitat,the nesting habitat is of lower elevation,more gently slope and more southeast\|facing aspect.In a special habitat,nesting area and non\|nesting area are also of great distinction.The nesting area is usually near to the edge of the habitat.The types of a special habitat's neighbouring habitats will affect pheasants'selection on some region in the habitat for nesting.

将多元统计学方法与地理信息系统结合对动物的栖息地进行适宜性分析 ,是近年动物栖息地研究者和管理者都十分感兴趣的方面。本研究采用马氏距离法 ,利用地理信息系统模拟甘肃雉鸡的营巢生境。模拟结果表明 ,与已知营巢生境相似水平为 0 .95的区域面积 ,仅占整个研究区的 0 .68% ,而与已知营巢生境迥然不同 ( P<0 .0 5)的区域面积占79.0 8%。营巢生境与非营巢生境在生境类型组成和地形因素上存在多方差异 ,营巢生境中农田和草坡占有极大比例 ,用于营巢的区域总是更接近生境的边缘。特别是接近于农田、草坡和白桦阔叶林等生境 ,表明倾向于在这几种生境的边缘附近营巢。营巢生境的平均海拔比非营巢生境低 ,坡度也较缓 ,坡向则更偏于东南方。在同一生境类型内部 ,用于营巢的区域和不利用的区域之间也存在很大差别 ,营巢区域总是更接近生境的边缘。某一生境周围的其它生境类型也会影响雉鸡的营巢选择。

We investigated the relationship between habitat use by crested ibis (Nipponia nippon) and human activities in Yang County, Shaanxi Province, China from 1998 to 2000.All nest sites, roost sites, and forage sites of crested ibis, which were distributed in this area of about 1 000 km 2, were located using the Global Positioning System(GPS). Data on the location of the bird, habitat topography, buildings, and wetlands were all imported into a GIS database. Comparison of the distances between the birds...

We investigated the relationship between habitat use by crested ibis (Nipponia nippon) and human activities in Yang County, Shaanxi Province, China from 1998 to 2000.All nest sites, roost sites, and forage sites of crested ibis, which were distributed in this area of about 1 000 km 2, were located using the Global Positioning System(GPS). Data on the location of the bird, habitat topography, buildings, and wetlands were all imported into a GIS database. Comparison of the distances between the birds ranges and human residences to those between control plots and human residences indicates that the crested ibis prefers to live near villages. In breeding seasons, the crested ibis nest sites, night roost sites, and foraging sites were all located around mountain villages; in wintering seasons, the birds night roost sites and foraging sites were situated in the Hanzhong Basin and nearby areas where human density was relatively high. The preferred habitats of the crested ibis are near wetlands and so are all human residences in this locality. We recorded the distance maintained by crested ibis between themselves and humans, and found that they tolerated farmers activities to some extent. They kept a significantly shorter distance from farmers than from strangers(Wilcoxon rank sum test, Z=-3 21, P <0 01). Crested ibis maintain a moderate distance between themselves and humans, and can therefore sometimes benefit from humans activities such as foraging for worms exposed by plowing. The fledging success of the crested ibis is high compared to that of many other birds. From 1981 to 2000 123 nesting attempts produced 363 eggs, 276(76%) of which hatched in turn producing 216 fledglings(78 3%). Based on data listed by Royle et al ., a mean fledging success of 56%( n =29) can be calculated, showing that fledging success in the crested ibis(78 3%) is much higher than in many other birds. We compared annual fledging success of the bird over twenty years with the mean distances between nest sites and nearest farmers houses, and found no correlation (r=0 28, P=0 24, n=35). In other words, there is no reason to suppose that the fledging success of this species is closely correlated with human activity. The altitude of crested ibis nesting habitat has reduced in recent years; average elevation decreased from 1 250 m in 1981 to 821 in 1999, meanwhile the average human population density increased from 22 people/km 2 to 55 people/km 2.This indicates that crested ibis prefers lower altitude nesting habitat with higher human density is undergoing population recovery in close proximity to human habitation. In summary, we concluded that the crested ibis has adapted to the human dominated ecosystem of Yang County.

1998到 2 0 0 0年间 ,我们在陕西省洋县应用样方法调查了朱 (Nipponianippon)活动区 (面积约10 0 0平方公里 )内所有正在使用的巢和部分往年的旧巢 ,以及主要夜宿地和觅食地 ,并将当地的地形、水系和居民区数字化 ,建立了地理信息系统数据库。通过对其空间位置的统计分析 ,发现朱显著倾向于在村庄附近栖息。朱的活动区与湿地的分布密切相关 ,而村庄都分布在湿地附近。朱与人类保持一定的预警距离 ,同时也对农民的日常活动表现出一定的适应性。我们分析了朱二十年来的繁殖成功率 ,发现它与巢址到农户的距离无关。而且 ,朱营巢的海拔逐年降低 ,其主要活动区正向人口更密的低海拔农村转移。因此 ,我们认为朱对以人类为主导的山村生态系统有良好的适应性。

Seven types of foraging habitats for Saunders' Gull were recorded: saltworks, Suaeda yhaura beaches, tidal grassland, aquatic ponds, farmlands, tidal mud-field, and rivers and streams. We compared the habitat availability with utilization in these seven habitats. The results showed that Suaeda yhaura beaches and tidal mud-fields were positively...

This article shows the characteristics of foraging and nesting habitats for Saunders' Gull ( Larus saundersi ) in Yancheng Biosphere Reserve. Seven types of foraging habitats for Saunders' Gull were recorded: saltworks, Suaeda yhaura beaches, tidal grassland, aquatic ponds, farmlands, tidal mud-field, and rivers and streams. We compared the habitat availability with utilization in these seven habitats. The results showed that Suaeda yhaura beaches and tidal mud-fields were positively selected by Saunders' Gull, and farmlands and rivers and streams were avoided. In the first phase of breeding period, aquatic ponds were also positively selected. The selection of Suaeda yhaura beaches and aquatic ponds changed heavily in different breeding periods of 1999~2000 and the selection of rivers and streams is stable. Three types of nesting habitats for Saunders' Gull were recorded: Spartina anqelieca community, Suaeda yhaura community and Aleuropus littoralis community. Suaeda yhaura community is the main nesting habitat for Saunders' Gull. The results of factor analysis indicates that factors affected nest-site selection for Saunders' Gull orderly are vegetation coverage and group degree, distance to human activity, biomass of zoobenthos and distance to water source, the contribution rate of them respectively is 26.23%, 20.55%, 14.82%, 14.02%.
