  1. The study investigated aboveground growths of caragana korshinskii and artemisia ordosica planted in four modes, revealing that in different planting modes their densities, heights and canopy width and biomasses remained unchanged or tended to decrease slightly ; the young shoots of a. ordosica annually grew in a s - shaped cure and the young shoots of c. korshinskii grew fast in spring and grew slowly or cease to grow from july on ; the biomasses and leaf area indexes of c. korshinskii and a. ordosica annually varied in a double peak curve and there were 8 annual plants that invaded in the four planting modes and formed higher coverage ; the quadrat with only a. ordoska appeared to have obviously lower coverage and biomass that the other three quadrats

    摘要對騰格里沙漠東南緣2種人工植被檸條和油篙在4種配置方式下地上部分的生長動態進行了研究,結果表明:不同配置方式下它們的密度、高度、冠幅和生物量本不變或略微呈下降趨勢;油篙新梢的年生長動態呈s型曲線,檸條新梢春季生長速度快, 7月份以後生長速度緩慢或本停止生長;檸條、油篙地上生物量和葉面積指的年變化均表現為雙峰型, 4種配置方式下共有8種1年生植物人侵,並具有高的植被蓋度;同其它3個樣地相,純油篙樣地1年生植物的密度、蓋度和生物量明顯
  2. Also the theoretical basis of the method have been checked through simple deducing simulation and the influences of various physical parameters on the method have been studied. it is shown that the method is theoretically reliable for the production oil wells without very high production rate and is more suitable in field production for oil wells ( i ) in area with bigger geothermal gradient ; ( ii ) producing fluids ( oil and water ) with distinguish thermal characteristics ; ( iii ) producing oil with lower heat capacity or water with higher heat capacity ; ( iv ) with good surface measurement accuracy, as well as the method h as certain requirements on the accuracy of the temperature and flowmeter logs sensors

  5. China is one of the countries which are harmed by storm surge both tropical and temperate cyclones, the disaster of storm surge can occure every seasons and from south to north in china ' s coastal area. based on the analysis of the features of temporal and spatial changes of storm surge disaster in the recent 50 years, this paper focuses on the frequency changes of historical records in recent 500 years and measured data in recent 50 years of storm surge disaster and the relationships between storm frequency change and climate fluctuation. meanwhlie, the effects of future increase in the frequency of tropical cyclones landing or affecting china and relative sea level rise with global warming on storm surge disaster of china ' s coastal area also discussed. the results show that, in recent 500 years, there are direct relationships between storm frequency change and climate fluctuation, i. e., high global mean temperature correspond with high storm frequency and low mean temperature correspond with low storm frequency. storm surge disaster in china ' s coastal area will be exacerbated with global warming

    中國是全球少幾個同時受臺風風暴潮和溫帶風暴潮危害的國家之一,風暴潮災一年四季,從南到北均可發生.本文於中國沿海近50年風暴潮災時間變化和空間分佈特點的分析,著重探討了近500年全國及長江、黃河、珠江三角洲的歷史記錄和近50年實測風暴潮災發生頻次的變化及其與氣候波動的關系,並對未來全球變化背景下,中國沿海風暴潮災的變化趨向進行了討論.結果表明:近500年來,中國沿海的風暴潮災在氣溫高的暖時段氣溫冷時段明顯增多.近50年實測臺風暴潮災的變化也是如此,而溫帶風暴湖的變化則與此相反.未來全球變化引起的登陸影響中國的熱帶氣旋頻次增加和相對海平面的上升,均將導致風暴潮災呈加重的趨向
