野外采样 meaning in Chinese
field sampling
Examples
- The gvg system is the sampling lineage system to extracting crop acreage information
Gvg系统是一种快速准确的野外采样系统。 - According to video - recording in the field and computing by making programs , several gravel parameters , such as perimeter , area , long and short axis etc . , were gained and the appearance coefficient and variety along the river were computed
通过野外采样录象，室内编程计算，初步得到卵石的周长、面积、长短轴等基本参数，计算了形状系数及其沿程的变化规律。 - The soil attribute data are built based on the second soil general investigation and samples got outside and analyzed inside . the assessment system of nanjing soil quality is built by taking advantage of principal component analysis and multiple linear regression equation
在第二次土壤普查资料和野外采样分析基础上建立土壤属性数据库，用主成分分析法和多元回归法对南京不同类型土壤进行生产潜力评价，建立南京土壤质量评价体系。 - The ecological study of macrofauna was conducted on four typical sampling stations selected in the northern muddy bottom area of jiaozhou bay , estuary of dagu river , culturing and nearby area in hangdao in mar . , jun . , aug . and dec . , 2002 . abundance and biomass of macrofauna were investigated by quantitative study . the macrobenthic community structure and biodiversity were analyzed through multivariate statistic analysis
本研究分别在胶州湾北部软底区、大沽河口、黄岛养殖区及养殖区邻域选取四个典型站位，于2002年3月、 6月、 8月和12月野外采样，对大型底栖动物进行了定量研究，采用多元统计方法分析了群落结构和生物多样性，探讨了底栖生物群落与环境因子的关系；用丰度和生物量比较曲线法分析大型底栖生物群落对自然和人为扰动产生的响应。 - The county of changling , located in the eastern edge of songnen sands , is a typical ecotone between agriculture and husbandry in northern china . in the viewpoint of land use / land cover change , it is an ideal district for research . in this thesis , we make use of the remote sensed data , the land use map , statistical data such as soil general data and field - measured data to analyze the land use change of changling county of the latest 20 years between 1981 and 2000 under the support of gis , and further we make some preliminary study on the impacts of land use change to regional climate and soil conditions
本文以位于松嫩沙地东缘、我国北方农牧交错带典型区域的长岭县作为研究区，利用遥感数据、土地利用数据、土壤普查资料和野外采样、室内测量等数据，在gis的支持下，对长岭县1981 - 2000年间的土地利用变化进行了研究，并在此基础上，探讨了土地利用变化对区域气候要素和土壤环境要素的影响，为长岭县土地利用优化策略的制定提供依据。
