白颈长尾雉栖息地小区利用度影响因子研究

1995年10月至1996年5月在浙江省开化县水坞山区采用无线电遥测技术和样方法对白颈长尾雄栖息地小区利用度影响因子进行研究，结果显示：（1）食物和水因子是决定白颈长尾雉栖息地利用度的最主要因子，随季节的变化，影响白颈长尾雉栖息地小区利用度的食物种类亦随之变化。（2）冬季，灌木层因子的作用大于草本层因子；春季，草本层因子的作用大于灌木层因子。（3）白颈长尾雉栖息地小区利用度多元回归模型：冬季：Y＝0．044438X1＋0．003519X2－0．001542X3＋0．074533；冬末春初：Y＝0．526660X1＋0．041444X2－0．005522X3－0．585041；春季：Y＝0．102324X1＋0．101763X2－0．002182X3＋0．120046。

Studies on the factors affecting patch use degree by Elliot's pheasant

Between Oct. 1995 and May 1996, the factors affecting patch use degree by Elliot's pheasant in Shuiwu, Kaihua, Zhejiang Province by radiotelmetry and quadrat sampling methods were studied. The results showed that the food and the distance to water were the most important factors determining the path use degree by \%Elliot's pheasant.\% The types of food influencing the degree of patch use varied seasonally. The effect of shrub layer on determining degree of patch use of \%Elliot's pheasant\% was more important than herb layer in winter, and the herb layer than shrub layer in spring. The models of Elliot's pheasant patch use degree are as follow. Winter:\%Y=0.044 438X\-1+0.003 519X\-2-0.001 542X\-3\%+0.074 533; late winter and early spring: \%Y=0.526 660X\-1+0.041 444X\-2-0.005 522X\-3-0.58 5041;\% spring: \%Y=0.102 324X\-1+0.101 763X\-2-0.002 182X\-3+0.120 046.\%
