3EROSION RATES ON UPLAND AREAS IN THE MIDSOUTH USA显示文摘This study documents the erosivity of rainfall, the high erodibility of soils, and reduction in annualand storm soil loss rates by conservation tillage at Holly Springs, Mississippi. Holly Springs is innorthern Mississippi in the Midsouth United States. Rainfall characteristic data and runoff dare wereexarmined for single storms and for cultivated fallow conditions for Loring (Typic Fragiudalfs) andLexington (Typic Paleudlfs) soils during 1963 through 1968 using data from 135 single storm events.Rainfall erosion index (EI) was the best single estimator among those rainfall characteristics studied to estimatC siol loss during the storms. Soil losses from a cultivated fallow plot were greater than 20 imaduring each of 10 storms. Average annual rainfall of 1314 mm and rainfall erosion index of 6315 MJmm (ha h)-1 during 1958 to 1976 for the 303-square kilometer Pigeon Roost Watershed near HollySprings, Mississippi illustrated the high erosivity of rainfall. Conservation tillage cropping systems forcom (grain and silage), soybean, cotton, and sorghum from 1974 to 1990 at Holly Springs effectivelycontrolled erosion, especially as compared to conventional-till. Soil losses from agricultural landpreviously under conventional-till were dramatically reduced. Cropping and management factor (SLR)values derived from selected large storms provided good estimates of annual SLR values for use in theuniversal soil loss equation.K. C. McGregor R. F. Cullum C. K.

17WATERSHED SEDIMENT YIELD AND RANGELAND HEALTH显示文摘Much of the western United States is considered to be rangeland. Rangeland areas produce a diverse mix of benefits and products, and their overall health, in an ecosystem context, is of national importance.Because sediment yield from a watershed is an integrated expression of all soil erosion and sedimentation processes occurring within it, it is logical that we seek to quantify and interpret sediment yield in the context of soil/site stability and watershed function as measures of rangeland health. Depth integrated suspended sediment samples were combined with runoff measured using flumes to calculate sediment discharge and yield from two experimental watersheds in the southwestern USA. Sediment yield estimates for individual runoff events were summed to produce estimates of annual sediment yield from these two rangeland watersheds. Estimated annual sediment yield data were then combined with the concepts of sediment delivery ratio and soil loss tolerance to assess soil/site stability at the watershed scale. Analyses suggest that using sediment yield estimates from distributed watershed processes with time-space averaged soil loss tolerance values is inconsistent. Thus, new distributed soil/site stability criteria are needed to replace the soil loss tolerance concept in assessing the health of rangeland watersheds. Sediment transport/yield models are used at interior points in a watershed to simulate distributed sedimentation processes. However, application of these models requires calibration and validation data and is thus dependent upon the availability of sediment concentration and yield databases. Therefore, additional efforts are required to build sediment yield databases through rescue of historical data along with continued measurement and monitoring at existing and new sampling sites.Leonard J.

18WOODY VEGETATION AND DEBRIS FOR IN-CHANNEL SEDIMENT CONTROL显示文摘Large woody debris and woody vegetation can exert a major influence on channel hydraulics and morphology, particularly in smaller (<30 m wide) streams. Although debris and vegetation have long been used for channel erosion and sedimentation control, scientifically-based guidelines for designers are scarce. Recent advances in understanding vegetative effects on flow and sediment transport are reviewed. The effects of vegetation on the flow field leads to enhanced deposition within and adjacent to vegetated zones, and possibly erosion elsewhere.Site factors must be carefully evaluated when designing vegetative treatments.F.

Cooper(Research Hydraulic Engineer and Supervisory Research Ecologist, respectively, U.S. Department of Agriculture,Agricultural Research Service, National Sedimentation Laboratory, Oxford Mississippi 38655-1157,shields s 2000International Journal of Sediment Research2000,15,1:0
19A STRONG LINK显示文摘Trade frictions should not affect the mainstream of Sino-U.S. mutually beneficial economic and trade cooperation China and the United States have a complicated relationship, one that can be called a competitive partnership. The U.S. trade deficit with China, its third largest trading partner, hit a staggering $201.6 billion last year, an imbalance that is a major bone of contention. Yet, while frictions over trade, intellectual property rights and other issues grab the headlines, there is strong-and grow...ZHOU SHIJIAN AND WANG LIJUN are respectively the standing councilor of China American Studies and associate professor at the Capital University of Economics and Business 2006Beijing Review2006,49,16:0
