October 2009 to November 2010, the National Nature Reserve of Jiangxi Guanshan dialogue pheasant, silver pheasant, spoon chicken, gray chest bamboo chicken and four kinds of pheasants habitat selection study investigated a total of 388 habitat The use of quadrats. Of principal component analysis to determine the four kinds of pheasants raw habitat selection main factor; card party (Chi-Square) test, nonparametric test (Kruskal-Wallis test) and discriminant analysis of four kinds of pheasants born throughout select a comparative study, in order to determine the impact of differences in habitat selection of four kinds of pheasants key factor; calculated the four kinds of vertical elevation distribution of pheasants and niche. The results show that: Guanshan Nature Reserve Elliot's pheasant, silver pheasant, spoon chicken and gray chest bamboo chicken and four kinds of pheasants altitude distribution between 200-1400m, each of them has its own in a relatively concentrated distribution range. Vertical niche breadth is 0.46,0.83,0.64,0.44; silver pheasant and spoon chicken niche overlap index up to 0.74 minimum, spoon chicken and Bamboo Partridge niche overlap index of 0.32. 2 using principal component analysis showed 17 variable factor of four kinds of pheasants, shrub cover, herb cover, herbaceous species, herbaceous quantity is the main factor of Elliot's pheasant habitat selection, forest type, aspect, shrubs, shrubs quantity Second major factor, the first six principal components contribution rate of 69.16%; arbor number of tree species is the main factor of the silver pheasant habitat selection, herbaceous number of species, herbs, forest type, aspect is the main factor, the contribution of the first seven principal components rate of 70.01%; tree cover, the number of shrubs, trees number of shrub height spoon chicken habitat selection factor, shrub cover, herb cover (s), herbaceous, deciduous layer coverage is followed by the main factors, the first seven main component contribution rate of 85.50%; herb cover, herbaceous number of deciduous layer coverage is a major factor in the Bamboo Partridge habitat selection, tree cover, tree species, tree quantity, altitude, forest type, aspect, shrubs, water distance is followed by the main factor, the first six principal components contribution rate of 73.29%. The chi-square test qualitative factors, four kinds of pheasants the slope upward there was no significant difference (P gt; 0.05), multi-bias sunny and semi-shaded slope. Silver pheasant, spoon chicken and gray chest bamboo chicken on the forest type differences white neck long tail pheasant and spoon chicken (χ2 = 18.204, P lt; 0.01) and gray chest bamboo chicken (χ2 = 13.723, P lt; 0.05 ) in forest types, there were significant or very significant difference. 15 quantitative factors nonparametric tests showed that the four pheasants in elevation, slope, tree cover, shrub cover, shrub number of shrub height, herb cover, herbaceous species, herbaceous number of deciduous layer cover and water distance of 11 quantitative ecological factors on the difference significant (P lt; 0.01), a significant difference (P lt; 0.05) arboreal species in the rest of the ecological factors, no significant differences (P gt; 0.05). 4, the canonical discriminant coefficient The results show that four kinds of pheasants habitat selection overlap to some extent, also the more obvious differences. By discriminant analysis of further research, the altitude, the number of herbaceous, shrub height, distance to water source, shrub cover, tree cover, slope, leaf litter, cover degree, shrubs quantity, herbaceous cover degrees such as 10 variable factor is the four kinds of pheasants habitat Select the differences between the key factor, the discriminant accuracy rate of up to 74.7%.
