| 1. | With 500 tonnage traffic capacity , zhangjing river is a golden line for water transport 张泾河通航能力达500吨,是水上运输的“黄金要道” 。 |
| 2. | Analysis of runoff and sediment variation and landscape pattern of typical watersheds in jinghe basin 泾河典型流域水沙变化及其景观格局分析 |
| 3. | The condition of water and sediment coming from jing - river influences directly the variety of erosion or deposit 泾河是渭河最大的支流,来水来沙条件直接影响着渭河下游的冲淤变化。 |
| 4. | Its sediment is from the upstream of linjiacun and jinghe river mostly , which is a tributary of the weihe river 泥沙主要来自支流泾河及林家村站以上地区,径流主要来自林家村站至成阳站区间流域。 |
| 5. | Dong zhuang reservoir is just the one which will be built on jing - river , which is a multi - sediment river and is the biggest tributary of wei - river 东庄水库是拟建于多泥沙河流泾河之上的一个水利枢纽工程。 |
| 6. | Study on the relationship between the pedogenetic environment changes and human impact in the holocene soil of the loess plateau in the upper reaches of jinghe 泾河上游黄土高原全新世成壤环境演变与人类活动影响 |
| 7. | B ) utilizing dong zhuang reservoir to adjust during on year . thus can decrease the sediment deposit of lower wei - river as result small flood and non - flood season 利用东庄水库调节泾河小流量洪水,进行年内调节,尽可能减少小洪水和非汛期小水对渭河下游的淤积。 |
| 8. | D ) utilizing dong zhuang reservoir to adjust the course of water and sediment of jing - river so as to coordinate the relation of water and sediment entering wei - river from jing - river 利用东庄水库对泾河水沙过程进行调节,使泾河入渭水沙关系比较协调等。通过这些措施可有效控制渭河下游淤积。 |
| 9. | Their downcuting velocity accelerates except luohe river round luochuan . the erosion velocity of weihe river round tianshui and jinghe river round binxian reduced , and the lateral erosion velocity of luohe river round luochuan reduced . this may be due to the reduced flow 天水渭南镇段渭河、彬县段泾河的侵蚀速率呈脉动式减小,秦家河段洛河侧蚀速率逐渐减小,这可能与河水流量随时间推移逐渐减小有关。 |
| 10. | The paper shows the research for the division of regional land - use structure in the east of gansu loess plateau according to the dates from the square and ratio of second - class land types of the detailed land - use investigation , adopting the quantified structure analysis method of landscape ecology , taking the longdong region of the upper and mid jinghe river - sheds as an example , through quantitative research of the division of regional land - use structure 摘要根据土地利用详查变更资料中二级分类的用地面积和比例,采用景观生态学结构定量分析方法,以泾河中上游流域的陇东地区为例,对土地利用结构的地域分异进行了定量研究。 |
