  1. 认为南水北调东线工程实施后,丰水年与常水年对长江河口水资源无明显影响;

    It is demonstrated that in high flow year and normal year , the northward water transfer has no significant influence on the water resources in estuary area ;

  2. 在丰水年干物质生产2.65kg/(hm2·mm);

    In an abundant precipitation year , the grassland 's dry substance yield averaged 2.65 kg / ( hm ~ 2 · mm );

  3. 结果表明,由于天津地势低洼易涝,地表水资源量大于35亿m3的丰水年,粮食减产;

    The analysis shows that in the year with surface water resource more than 35 × 109m3 , the grain yield decreases , because there is a lot of water logged lowland in Tianjin ;

  4. 平水年,深根系区与浅根系区土壤水分变化差异表现在30cm深度以下,而丰水年其差异主要表现在土壤表层(0~30cm);

    The large differences on soil water between deep-root and shallow-root plant plots could be seen in the surface layer ( 0 ~ 30 cm ) in rainy year , but under 30 cm depth in average year .

  5. 厄尔尼诺事件与浙江丰水年的关系

    Relation between El Nino event and wet year of Zhejiang

  6. 浙江省丰水年和大洪水的变化趋势

    Study on the Trend of Wet Year and Large Flood of Zhejiang

  7. 西安地区丰水年有林地土壤水分恢复效应研究

    Restoration effect of soil moisture content under woodlands in Xi'an region in wet year

  8. 同时,我们还专门对丰水年和枯水年的水资源状况进行了研究。

    Water resource for high flow years and low flow years is also discussed .

  9. 特大丰水年洛川人工林地土壤水分特征研究

    Research of soil water character below artificial forest of the heaviest rainfall year in Luochuan area of Yan'an

  10. 二是降水,尤其2002年和2003年是明显的丰水年,降水量的显著提高将更有利于植被的恢复。

    Secondly , the distinct increase of rainfall especially in 2002 and 2003 contributed greatly to restoration of vegetation .

  11. 丰水年3水处理(拔节孕穗扬花水)和次水年4水处理(拔节孕穗扬花灌浆水)可以获得较好的经济效益和社会效益。

    In rich water year , the treatment of film mulching water 3 can get better economical and social benefit .

  12. 无论平水年还是丰水年,深根系区土壤水分变幅均比浅根系区大。

    The variation ranges of soil water in the deep-root plant plots were wider than those of shallow-root plant plots .

  13. 西安地区丰水年之后人工林地土壤水分恢复与消耗

    The Soil Moisture Content Restoration and Consumption of the Artificial Forest and Farmland in Xi'an Area after a Rainy Year

  14. 西安南郊曲江丰水年苹果林地土壤干层恢复

    Reconstruction of dried layer under apple tree plantation at Qujiang in Southern of Xi ′ an City with plentiful raining year

  15. 奉节只有丰水年适宜在坡度较小的耕地上种植麦-玉-苕、胡-玉-苕和麦-玉-豆。

    As Fengjie there was just wheat-corn-sweet potato , horsebean-corn-sweet potato and wheat-corn-soybean could be planted on smaller slope land in wet year .

  16. 丰水年,土壤水分收支正平衡,但入渗雨量的大部分(>80%)为强烈蒸发蒸腾所消耗。

    In rainy year , soil water storage increased , but most infiltrated rainfall ( more than 80 % ) was consumed by intensive evapotranspiration .

  17. 在丰水年和旱年,土壤温度与水分均与微生物总数和微生物生物量显著正相关;

    The cooperation between soil moisture and soil temperature was changed , and it correlated significantly with soil microorganism population quantities and microbial biomass in two years .

  18. 地表水的污染风险大于地下水,稻季的污染风险大于麦季,丰水年的污染风险大于平水年。

    The risk is higher to surface water than to groundwater , in the rice season than in the wheat season , and in years with excessive rainfall than in those with normal rainfall .

  19. 丰水年极端降水后土壤干层消失,水分得到很好的恢复,原来的土壤干层所在层位恢复后的水分含量明显高于其上部和下部。

    In abundant water year after extreme precipitation the soil dryer vanishes , the soil moisture restores well , and the moisture content in the original dryer is obviously higher than the upside and lower part .

  20. 在平整的耕地上,奉节丰水年和平水年适宜的单作作物为红薯、玉米和大豆,欠水年没有最适宜的单作作物,可以选择较适宜的小麦和油菜。

    In the flat farmland , sweet potatoes , corn and soybeans were appropriate to plant in wet and average year , wheat and rape could be chosen in dry year as a few suitable crops in Fengjie .

  21. 分析认为,潮汐河口为了应对连续丰水年和连续枯水年交替的径流改变,通过长周期泥沙冲淤和河床变形进行自动调整,达到冲淤平衡。

    It shows that tidal estuary could get equilibrium by the auto-adjust function including long-period sediment erosion / deposition and deformation of riverbed in order to correspond to the runoff change between continuous high flow years and low flow years .

  22. 结果表明:严重干旱情况下,氮、磷、钾及有机肥的增产效应都大幅度降低,从而使产量水平仅为142.1kg/亩,较丰水年(1995~1996年)减产57.4%。

    The results showed that : ( 1 ) Yield increasing effects of nitrogen , phosphorous , potassium and organic fertilizers are significantly decreased under extremely dry condition . The decreasing rate can reach up to 57 . 4 % .

  23. 流域内两类污染负荷所占比重大体相当,枯水年点源污染比重略高,而丰水年非点源污染比重较大。

    The proportion of the two pollution loads in the basin is more or less the same , point source is slightly heavier in a dry year and the proportion of non-point source pollution is greater in a wet year .

  24. 丰水年苹果林地2~4m的土壤含水量在23%以上,远远高于正常年份同一层位的土壤含水量,这说明该地区的土壤干层已经消失。

    It is shown that dried layer of soil has developed in this area . The result shows that the moisture content of 2 ~ 4 m under the ground is more than 23 % , far higher than that of the normal annual .

  25. 不同水文年的丰水期硝氮浓度以丰水年最高,平水年次之,枯水年最低。

    The concentration of nitrate in high water season in wet years is highest , in mean year take the second place , and in dry year is lowest .

  26. 尤其是森林在调节丰水季节与枯水季节、丰水年与枯水年的河水流量,以及在减免洪水泛滥和土壤侵蚀方面,功能效益十分突出。

    It is obvious that forest can conserve water resource and soil , especially can adjust the flux in the season or year of water-in-abundance and water-in-deficient , and decrease flooding and soil eroding .
