陕西省鹿类动物的数量估计和资源保护与利用问题的探讨
Estimation of populations and discussion on protection and exploition of deer in Shaanxi province
【摘要】 通过74个样方共55.17km2,分别对陕西分布的4种鹿类动物中的3种的种群数量进行了调查,借助数理统计学方法,对其资源贮存量进行了估计.结果表明,林麝(Muschusberezovski)1985年的密度是2.49±0.37只/km2,秦巴山区的资源估计贮存量为85200±10400只;1983~1984年黄麂(Muntiacusrevesi)的密度为9.80±0.75只/km2,安康地区10县黄麂资源存量为64700±4900只,年种群自然增长率为35%,适宜猎取量为13000~14000只;陕北黄土高原狍(Capreoluscapre-olus)1976年的密度为6.02±0.83只/km2,资源贮存量为81200±11200只.1981年狍的密度为5.09±0.61只/km2,资源存量为68700±8200只,狍的年种群自然增长率为38%,适宜猎取量为12000~15000只.文中对陕西省鹿类动物资源的保护、管理和利用进行了探讨.
【Abstract】 Of the four wild species of deer named Musk deer (Muschus berezovskii), Muntjac deer (Muntiacus reevesi), Poe deer (Capreolus capreolus), Tufted deer (Elaphodus cephalophus) are indigenous to Shaanxi Province. Only one species of deer, Roe deer, occurs in Loess Plateau in the northern part of Shaanxi province, and the other three species of deer are well distributed throughout the Qinling and Bashan Mountain areas in the southern part of Shaanxi Province. Based on the investigation of 74 various sample plots in 1976,1981,1984 and 1985 and available harvests data in the last thirty years the populations and the densities of Musk deer, Muntjac deer, Roe deer are estimated as follows: In 1985 the density of Musk deer is about 2.49±0.37 km-2 and the population is estimated to be about 83 000 to 113 000 in that year. Hunting of the Musk is forbdden and it is protected by the law in China. Muntjac deer has a wide distribution and It is plentiful in the southern part of this province. In 1983 the density of the Muntjac was about 9.80±0.37 km-2 and it was estimated that the total stock of the muntjac was about 60 000 to 70 000 in Ankang Reging. The population growth ratio was 35% in this year and the suitable number for hunting would be 13 000 to 14 000. In 1976 the density of the Roe deer in Yan′an Region was 6.02±0.83 km-2 and the Roe pupulation was estimated to be about 7 000 to 92 000 and in 1981 Roe density was 5.09±0.61 km-2 and the pupulation was around 60 000 to 76 000. The Roe population growth was 38.1% and the suitable number for hunting would be 12 000 to 15 000 in this year. Based on the harvest data, about 3 000 to 4 000 Tufted deer were killed each year before 1984. and no any recent information is available but it would to be rare in mach of this range. On the basis of the biological character of the deer, the measures are discussed for management, protection and exploitation of the Deer in Shaanxi province.
