论黄河泥沙的综合开发利用

黄河泥沙资源丰富。如何处理黄河泥沙,历来是黄河治理开发的大事。该文结合黄河下游山东、河南两省的实际情况,在论证综合开发利用黄河泥沙的可能性、技术支撑、市场需求、法制环境等基础上,提出了淤改涝洼地、制造墙体材料、复垦采煤塌陷区等综合利用黄河泥沙的建议。     

梁山县试点引“黄”淤改涝洼地项目

2011年以来,梁山县在省级大路口基本农田整理项目区试点利用黄河泥沙淤改项目区内涝洼地,取得了明显的经济、生态和社会效益,增加有效耕地面积48．67余公顷。项目的实验成功,为下步采煤塌陷地治理和土地复垦整治探索出了一条新路子。     

黄河大柳树水利枢纽工程区生态修复绿水资源消耗量定量模拟

绿水的确定和有效利用对于干旱半干旱地区水资源配置和生态建设有重要的意义。在绿水概念界定基础上,构建基于生态水文理论的绿水资源消耗量定量模型,并以大柳树水利工程区为研究对象,对工程区20世纪50年代以来绿水资源消耗量进行定量模拟,得到研究区绿水资源消耗量现状时空结构特征,进而得到不同水分供应条件下不同植被类型绿水资源消耗定额,确定生态修复措施下工程区的绿水资源消耗量。结果表明:(1)大柳树水利枢纽工程区绿水资源消耗量受降水影响明显,50年代以来整体上表现出增加到降低的变化趋势;(2)不同植被类型绿水资源消耗量差异明显:林地最大,其次为农用地;(3)大柳树水利枢纽工程区不同水平年绿水资源定额,其中枯水年:林地341.2 mm,灌丛241.1 mm,草地200.8 mm,农用地291.5 mm;丰水年:林地444.4 mm,灌丛306.1 mm,草地271.2 mm,农用地399.9 mm;平水年:林地370.3 mm,灌丛295.3 mm,草地250.6 mm,农用地360.6 mm;(4)根据各水平年不同植被类型绿水资源定额以及工程区生态修复方案,利用面积定额法得到工程区各生态修复措施需水总量及工程区各分区生态...     

“黄河的治理”教学中的情感教育

“黄河的治理”一课是初中地理一节公开课的课题。和之前所有的公开课一样,准备的过程忙碌而快乐。然而,课前的准备工作却让我越来越感觉到头皮发麻,精神紧张：1、准备收集材料,足足做了40张幻灯片（内容涵盖面大,包括四个大方面的内容）;2、学生的情感准备有空缺（南方学生对黄河的陌生和未知,导致对黄河难以融入感情）。

黄河是中华民族的“母亲河”,它以流域跨越省份多、涉及地名众多而著称。     

Sediment flux and source in northern Yellow Sea by^210 Pb technique

1 INTRODUCTION The Yellow Sea is a shallow epicontinental sea surrounded by Chinese mainland and Korean Peninsula. It is connected with the East China Sea to the south, and with the Bohai Sea to the north- west. Water depth is generally less than 80 m with average of 44 m (Qin et al., 1989). The major sediment sources are the Huanghe and Changjiang (Yangtze) Rivers, providing annual sediment load of about 1.1×109 and 4.9×108 tons, respectively. A maximum of 1.6×108 tons of sedime…     

黄河下游一期标准化堤防建设刍议

黄河下游一期标准化堤防建设，即对黄河下游堤防进行加高加固，在临河种植50m宽的防浪林，按照2000年设防标准，将背河淤区淤宽至100m，按株距2m、行距3m种植适生林；堤顶加宽至10～12m，铺筑6m宽的沥青路面，并与堤下防汛公路、辅道相连，确保抢险车辆的顺利通行；对凹凸不平的堤坡进行处理，清除老化草皮，并进行新植，确保草皮覆盖率达到95％以上。黄河下游山东段标准化堤防第一期工程为东明重点防守段和济南市区，长度为128km，截至2005年6月底，菏泽、济南全部完成标准化堤防建设任务。

Changes in Huanghe （Yellow） River estuary since artificial re-routing in 1996

With the combination of historical data, field observations and satellite remotely sensed images(Landsat TM/ETM and CBERS), changes in Huanghe (Yellow) River estuary since 1996 when artificial Chahe distributary was built up were studied, mainly including water and sediment discharge from the river, tides, tidal currents, suspended sediment diffusion, coastline changes and seabed development. During following six and half years (up to the end of 2002), runoff and sediment loads into the river mouth declined dramatically. At the beginning of the re-routing, abundant sediment loads from the river filled up nearshore shallow water areas so that the newborn delta prograded quickly. With rapid decrease of sediment loads transported to the estuary, the delta retrograded. In 1997, subaerial tip of the abandoned delta receded 1.5km; its annual mean recession rate was about 150 m in following years. In addition, marine dynamic condition near the artificial outlet had also changed. Under the interaction of ocean and river flow, most of incoming sediment loads deposited in the vicinity of the outlet. Seabed erosion occurred at the subaqueous delta front. Between 1999 and 2002, erosion thickness averaged at 0.3 m in the subaqueous delta of 585.5 km2.
