摘要
利用以前卢氏、西峡、淅川和内乡4个县的麝香收购数据,建立林麝种群逻辑斯蒂方程。在考虑收获率的情况下,计算出平均分布密度,经与采用小样本抽样定值估计法得到的密度进行统计检验,结果无显著性差异。根据函数的极值理论,资源量在1048只时,函数有极大值261只/年,为最大持续产量。
Using the musk purchase data in Lushi, Xixia, Xichuan, Nixiang 4 counties, Author establishes the forest musk deer population logistic equation, calculates the average density of distribution in consideration the harvest rate .through statistical examination between the density by using the small sample sampling def＇mite value ,the result does not have the significance difference. According to function extreme value theory, the function has maximum value 261 per year, is the most greatly sustainable yield when resources quantity is 1,048.
