The first part took temperature,moisture,pH and C/N ratio as the main technological index to make sure the befit compost condition of quantity of inoculant, moisture,pH and C/N ratio.

第一部分以温度、水分、pH值、C/N比为主要研究技术参数，通过这些参数确定适合畜禽粪便高温好氧堆肥的VT菌剂的接种量、水分条件、pH值条件及C/N比条件。

Adopting the method of dynamic layout, it researches the irrigational rule'soptimization method of many stages under the condition of lacking water resource.

对于作物水分生产函数的研究采用了Jensen模型，结合试验数据分析水分亏缺对作物产量的影响，采用多元回归分析法求解模型参数。

Thus,the principle and methods for widening the ranges oftime and space for applying water production function of rice and principle and methods fordrawing the isogram of WSI based on the isogram of ET0 and the soil map have beenestablished.

通过参照作物需水量及其频率以及不同地区土壤有效含水量为媒介，建立了对水分敏感指标在不同水文年份和不同地区进行预报的数学模型，据此提出了水稻水分生产函数在时、空两方面插补、延长、移用与扩展的理论与方法。

Effects of repeated cycles of dehydration\|rehydration on gas exchange and water use efficiency were studied in one\|year\|old jack pine Pinus banksiana Lamb.

该文研究了多重复干旱循环对1年生北美短叶松和黑云杉苗木的气体交换速率及水分利用效率的影响。结果表明，多重复干旱循环对它们的气体交换有显著影响（P＜0.5），而对其水分利用效率影响不大（P＞0.1）。

However,it is short of profound study on the aspect of modeling and analyzing the soil water movement in karst area.

土壤水分是生态环境中水分存在的主要形式之一，是喀斯特生态环境脆弱区生态恢复的主要限制因子。

Water is one of the main factors limiting plants' growth and distribution in most areas of North China.

在中国北方大部分地区，水分始终是影响植物生长和分布的最主要限制性因子之一，植物在其生长期经常遭受水分胁迫。

Daily and seasonal variations of dominant plant species transpiration rate are distinct in the research area, and the transpiration rate is lineally relevant to environmental factors. The evapotranspirations of plant species are different in sandy plant communities of the research area. The position of water deficiency layer in all the communities soil isinfluenced by position of the water moisture severe fluctuation layer and dense root systems layer.

研究区主要植物种蒸腾速率日变化和季节变化明显，蒸腾速率与环境因子呈线性显著相关；研究区植物群落蒸散量随植物种类而不同；各群落土壤水分亏缺的空间分布与土壤水分剧烈变化层、根系密集分布层相吻合，季节动态则与植物物候期密切相关。
