SEDIMENT HAZARDS IN THE LOWER YELLOW RIVER

引用

International Journal of Sediment Research 1999年第2期14卷 25-30页

作者： SHI Changxing (Supported by the National Natural Science Foundation of China) (institute of geography,{2., China)

The main sediment hazards in the lower Yellow River are flooding, channel erosion, desertification of cultivated lands, waterlogging. and soil salinization. Some of the hazards are the direct results of sediment movement and the others are related with sediment movement by the special landforms which themselves are the results of sediment movement. On the one hand, the sediment hazards,such as flooding. bank erosion and soil salinization, are aggravated by serious sediment accumulation in the Yellow River channel and irrigation canals due to heavy sediment load of the rived On the other hand, the distribution of the sediment deposit of different grain sizes is also a main factor influencing flooding, desertification, waterlogging and soil salinization hazards. The paper suggests to change the distribution of sedimentation as a measure of mitigating sediment hazards.

Research of desert science in China began in the 1930s, when Chen Zongqi et al. first made apreliminary investigation in several deserts. Shortly after the founding of the People’s Republic ofChina a few studies were carried out to meet the demand for the establishment of windbreak andsandbreak forests, for example, the studies of moving sand dunes in Yulin.

作者： Qi Zhang State Key Laboratory of Lake Science and Environment nanjing institute of {2. and limnology {4. academy of sciences nanjing 210008 China Jinling Yang institute of Soil Science {4. academy of sciences nanjing 210008 China

This paper tested the effects of refined soil property on the hydrological modelling results, exemplified in the surface runoff-groundwater coupled model for Xitiaoxi catchment, Lake Taihu basin, by extending the previous study where a relatively coarse soil map was used. This study finds that the refined soil property, associated with a finer model grid size significantly improves the accuracy in modelling the stream flow for dry seasons, when the groundwater base flow （groundwater discharged to rivers） dominates the stream flow. Since the groundwater base flow is highly dependent on the soil water percolation processes, the accurate simulation of base flow requires an accurate representation of the soil property and soil water processes. This finding implies that the soil resolution may affect the partitioning of surface and subsurface water flow, and should be appropriately considered in coupled simulation of surface and subsurface water flow, especially for the cases that stream flow simulations for dry seasons demand for a high accuracy.

The role of aerial algae in the formation of the landscape of the Yunnan Stone Forest,Yunnan Province, China

Aerial algae on the surface of carbonate rocks at the Stone Forest, Shilin County, Yunnan Province, China, and their bioerosion were investigated in the field and studied in the laboratory in detail. Through the observation, identification and statistics of more than one hun- dred algal samples and rock samples with the optical microscopes (stereomicroscope, biological microscope) and the scanning electronic microscope (SEM), the relationships between erosional forms on the surface of the Stone Forest and algae and/or algal communities and the genetic mechanism for the formation of erosional forms were analyzed. It is suggested that aerial algae play an active role in bioerosive processes that may affect the formation of karst erosional forms. These effects include both direct and indirect ones. The direct effect is the initiative control (algal shape-controlling role) of algae on the formation of karst forms of various scales, mostly mi- cro-scale (<10-3m) and minor-scale (10-3-10-1m) erosional forms. The algal shape-controlling roles can be divided into the algal individual shape-controlling role and the algal community shape-controlling role. The former mostly controls the formation of micro-scale erosional forms, while the latter mostly controls the formation of micro-scale and smaller minor-scale erosional forms. The indirect effect refers to the promoting role of algae in the formation of karst forms, which may affect the formation of karst forms of all types and scales. The bioerosion of algae accelerates the weathering process of the whole Stone Forest karst landforms.

Approaches to the systematic tourism planning-a case study of the Ningxia Hui Autonomous Region

Journal of Geographical sciences 1999年第4期9卷 362-370页

作者： LIU Feng(institute of geography,{2., Beijing 100101, China)

The rapid development of tourism makes a further demand for tourism planning in China. It is necessary to find out some new effective approaches and patterns to guarantee the continuity andpracticality of the planning. The approach of systematic tourism planning is a way along this *** paper advances the theory that the tourism planning is in fact the Systematic tourism planningand that the planning must take into account the operation of the whole tourism system and befocused on the general optimization of all the subjects concerned. Besides, the planning should bemulti-dimensional. must optimize and balance the economic, environmental and social-culturalfactors in achieving sustainable development and must be monitored to ensure the accomplishment ofthe objectives and the implementation of the recommended policy. The systematic planning shouldalso embody a continuity or a guideline of progressiveness, with an adaptability to the possiblechanges in the future . The paper, with the Ningxia Hui Autonomous Region as a case, gives a briefpresentation of the overall theoretical pattern of the systematic tourism planning, the essentialelements in the systematic planning and the practicable approaches.

Using the 1°×1° NOAA AVHRR NDVI data set in China, an index on the spatial different gradient of landcover is created. Then based on the index and supported by the geographical information system, it is revealed through principal component and factor analyses methods that there exist four types of seasonal patterns of spatial differentiation of landcover change in China, i.e. November to next March type, June to September type, May or October type and April type.

Journal of Geographical sciences 1999年第2期9卷 105-115页

作者： CHEN Hao(institute of geography,{2., Beijing 100101, China)

The slope-gully erosion relationship in small catchments of the middle reaches of the Yellow River has long been a topic concerned by relevant departments in China Slope-gully relationship in typical small catchment is determined determined on the concept of net increase of sediment yield by using analytical method of sediment formation at different positions in the catchment The result shows that sediments in a small catchment in the middle reaches of the Yellow River mainly come from slopes. ms paper indicated that the sediment sources from slopes are roughly 55, 60, 78 and 85 % of the total sediment yield of a small catchment in Yangdaogou. Wangjiagou. Jiuyuangou and Nanxiaohegou, respectively, due to impacts of varying degress from slope runoff.

Longitudinal dunes are the most widespread dune types in the world sand seas but comprehensive study on the sand surface stability is scarce. The southern part of Gurbantnggt Desert is mainly covered by longitudinal dune in which fixed and semi-fixed dunes occupy over 80% of the total area. Systematic analysis on the climatic conditions, the soil moisture and vegetation distributions, and the sand surface activities showed that the fixed and semi-fixed dunes are in a comprehensive low-energy wind environment. Snow cover and frozen soil provide a good protection to the ground surface in winter. The temporal distribution of precipitation and corresponding variation of temperature create a favorable condition for the desert plants growth, especially for the ephemeral plants. The occurrence of effective winds for sand moving in April to June coincides with the stage of relatively wet sand surface and good vegetation cover, which effectively keep the sand surface stable at the interdune and the plinth of the dunes. Activity sand surface appears only at the crest and the upper part of the sand dunes.
