查询词典 water area

Based on nitrogen concentrations of different forms, total phosphorus and soluble phosphorus in the surface water, nitrogen and phosphorus pollution sources were further explored by means of a field undisturbed tension-free monolith lysimeter(1 m2 in area and 1 m in depth)in combination with the 15N-tracing method.

随着工农业生产的快速发展，人口的急剧增加和化学肥料使用量的增加以及生活污水的直接排放，河流、湖泊等地表水体的氮磷污染有加重趋势，如北方的辽河、汾河、海河及淮河，南方的黄浦江、太湖、巢湖、滇池等都遭受严重污染[1￣3]。

Four groups of experiments with different level--indoor simulation experiments, lysimeter experiments, pot culture experiments and field plot experiments-- were carried out to systematically study the environmental effects following the application of fermentation sludge to farmland in Tianjin area, which include soil salinity and potential contamination on ground water, and to primarily investigate the fertility of NovoGro in agricultural soil.

本论文通过四组不同层次的实验—室内模拟实验、渗滤实验、盆栽实验和小区实验，首次对酿造污泥农业利用可能产生的环境影响：1NovoGro对土壤的盐分效应；2NovoGro对地下水的潜在污染，进行了比较系统的研究，同时对NovoGro的肥效特性也做了初步的探讨。成功地解决了制约酿造残渣在天津地区农业利用的关键问题，为酿造污泥的综合利用提供了科学的依据。

In this paper,we took an area of agriculture and pasturage interlaced zone of northern ShaanXi as an example and discussed the method of principal components analysis to improve the accuracy of water body information of TM image.

以陕北农牧交错带为试验区，采用主成分分析法对TM图像进行增强，然后应用最大似然分类法提取水体信息，并将提取的结果与单纯依靠最大似然分类法得到的结果进行了对比。

Distribution of biogenic silica content in surface sediments from deep water areas showed that it could not only reflect the paleoproductivity of siliceous micropaleontology in surface waters, but also indicate the strong or feeble upwelling. Thus, it was further confirmed that using biogenic silica content in sediments to trace upwelling and its change was effective and reliable. The analyzed result showed that radiolaria and poriferous specula have more contribution for biogenic opal, comparing with diatom in surface sediments from the northern studied area, probably owing to the diatom dissolved easily away and eaten by other organisms with little effort.

深水区表层沉积物中生物硅的含量分布表明，其不仅能反映出表层水体中硅质生物的古生产力水平，而且还能指示上升流的强弱，从而进一步证实了利用沉积物中生物硅含量来追踪上升流发育和变化的有效性与可信度研究结果还显示，在研究区域中北部表层沉积生物硅中放射虫和海绵骨针较硅藻占有更大的比重，这可能是由于硅藻易被溶解并易被其他生物体摄食的缘故。

This paper took the paddy soil after saving-water irrigation as the object,which is from Taian town of Yangzhou city, selected microtomy to get undisturbed soil samples respectly between two periods(before irrigation and after harvest), built up the analytical technique of numerical picture system.It also set up the analysis index of macropore structure,such as the number of macropores N, the macroporosityφ,the area A, the perimeter P and so on. Meanwhile make analysis contrast about horizonal distribution among 4cm, 6cm and 8cm scanning areas, vertical differences per 2cm unit and contrast in time between different periods.

本文选取扬州市泰安镇节水灌溉后稻田土壤为研究对象，采用切片法取开灌前和收割后的原状土样，运用数字图像制备技术，获取大孔隙数目N、大孔隙度Φ、面积A、周长P等分析指标，对4cm、6cm和8cm扫描直径内大孔隙作水平向差异性分析，对2cm单位深度上作垂向差异性分析以及对两个不同时期作时间差异性分析。
