褐马鸡非损伤性取样、微量取样DNA提取的初步研究

野生动物学报, 2010
褐马鸡是中国特有的国家Ⅰ级保护濒危鸟类,为了解决野生褐马鸡分子生物学研究中存在的取样局限性,采用非伤害性取样和非损伤性取样,对褐马鸡微量血液、皮、脚垫、指甲、羽毛、陈旧标本的皮以及粪便的DNA提取进行了初步研究。结果表明,从褐马鸡微量血液（10μL）中可以提取到浓度和纯度高的基因组DNA（41.85μg）;从褐马鸡的皮、脚垫、指甲、羽毛中可以提取出基因组DNA并扩增出目标片断;陈旧标本的皮能够提取到基因组DNA。该研究将拓宽褐马鸡分子生物学研究的采样范围,并可以提高野外非损伤性取样在保护遗传学中的应用。

基于高分7号卫星DEM的坡度坡长计算精度评价

Shuitu Baochi Xuebao
[目的] 坡度和坡长作为重要的地形因子,其计算的准确性直接影响坡面土壤侵蚀模型的评价精度。高分7号卫星的高精度高程测量能力在地形因子的准确提取上具有较大潜力,期望能将其利用到坡度和坡长提取之中,实现对地形的准确表达。这需要对利用高分7号卫星DEM提取坡度坡长的结果进行精度评价。[方法] 利用地形因子(LS)计算工具,对陕西省吴堡县4个小流域高分7号卫星、1∶10 000地形图、激光雷达影像生成的DEM进行坡度、坡长的提取。采用相关系数(r)、相对偏差和绝对偏差作为评价指标,评价高分7号提取地形因子的精度。
