摘要
本文全面总结了我国野生动物调查的主要方法及应用,分析了已有方法在应用中的问题和缺陷,介绍了国际狩猎场的盘羊资源调查方法——地图样带法,并比较了该方法与样线法得出的调查结果差异和两种方法在实际应用中的区别。地图样带法没有长度和宽度概念,也没有规定样带的既定形状,提供了一种确定调查范围和计算样带面积的便捷方法,解决了过去调查中样带面积计算的难题。该方法完全根据实际调查的区域和地形地貌来确定样带的范围,使调查更具灵活性、机动性,并使密度的计算回归到了其本身的意义。该方法没有技术门槛,对广大基层野生动物保护工作者更具可操作性。
We summarized the methods and application of wildlife surveys in China, and analyzed the problems and faults with these methods. We introduced the method of map strip sampling which we used in a survey of argali resources in all international hunting grounds, and compared the results and differences in application with line transect sampling. Map strip sampling has no length and width ; it also doesn＇t require the fixed shape of sample. The method provided a convenient way to determine the region for survey and calculated the area of the strip sample, thus resolving problems with calculating the survey area in past work. Compared with line transect sampling, this method is more flexible and operational, and more consistent with the actual situation. It makes the calculation of density return to its original meaning. The method has no threshold on technique and is better and easy to understand and operate for all local staff of wildlife conservation.
