To advance the estimation precision, in this paper, we classed land cover into four layer, canopy of Robinia pseudoacacia L ,top of Melilotus albus Desr,bottome of Melilotus albus Desr and layer of soil, separately estimated their fluxes of moisture, heat and CO2 ,actualized the separated simulation for each composement in soil-vegetation-atmosphere contimuum.

同时，本次研究强调了太阳辐射在冠层间的辐射传输机制，为了提高估算精度，本文把地表覆盖分为刺槐冠层，草木樨上层、草木樨下层及土壤层四个层面来分别估算其水热及CO2通量，做到了土壤-植被-大气连续体能量及物质通量的分离模拟。

Soil CO2 efflux declined by approximately 20% in 1 year after both girdling and HWA infestation, even after accounting for the intra-annual variability of soil temperature and moisture.

土壤CO2射流下降了大约20%在一年之后，即使是围绕和华出没的变化后的土壤温度、奎屯河水分。在土壤和减少并发下跌，白，站得细根生物量建议迅速下跌，从叶。

Based on the measurement and analysis of CO2 concentrations in soil profile, soil temperature and moisture, Some results could be outlined as follows.

因此，我们需要正确理解温度和水分对土壤CO_2浓度的影响，这在预测土壤呼吸对于气候变化的响应方面特别重要。

The mechanical strength of paddy soil in rice stubble field changed greatly with changing soil moisture content.

稻茬田土壤抗机械强度随含水量变化的曲线的坡度很大，麦茬田则较小。

450M, 1650m, 1850m and 2050m it is 54.04mm, 42.8mm, 56.38mm and 66.22mm respectively, showed in typical this world lay aside of moisture of slope upside soil is measured the biggest, of declivous seating arrangement, the region with moisture the poorest condition gives the slope in now.

结果表明：海拔1450m、1650m、1850m和2050m的0~50cm土层的年平均贮水量分别为54.04mm、42.8mm、56.38mm和66.22mm，表明了在典型阳坡上部土壤水分贮量最大，下坡位次之，水分条件最差的地带出现在中坡。

It can provide some theoretic gist for resource value of water and soil in sandy land to indicate the change and law of soil moisture character, as well as the water circulation and balance mechanism in sandy land, at the same time, it have important practical significance to protect limited water resource, improve using efficiency of water resource,control desertification, choose and educate sand binding plant, renew and restore degraded ecosystem, as well as the economy benefit of irrigative agriculture and intending trend of development.

揭示沙地土壤水分特征的变化规律以及沙地水循环和平衡机理，可以为沙地水土资源评价提供一定的理论依据，同时对于保护当地有限的水资源和提高水资源的利用效率，以及沙漠化防治，固沙植物的选育，退化生态系统的恢复与重建，灌溉农业的经济效益和未来的发展趋势都具有重要的实践意义。

A laboratory incubation experiment was conducted to study the effect of soil moisture on N2O flux from loessial soil in northwest China.

通过室内模拟试验，研究湿度对西北地区黄绵土N2O排放的影响。

The result showed that when soil moisture content is 90% of the relative moisture content,it resulted in an increase in plant dry substance accumulation and strong seedling index ,a reinforce in net photosynthetic rate and root vitality ,and a decrease in transpiratory rate ,compared with the nmrmal irrigation which is 100% of th...

结果表明，土壤含水量为相对含水量的90％（PF值1.6），较常规灌至土壤相对含水量100％，植株干物质积累增大，壮苗指数提高，光合速率、根系活力增强，蒸腾速率降低。因此认为番茄苗床灌溉土壤含水量最佳上限为90％。

Field moisture capacity is the key factor not only resulting in afforestation success or failure, but also that impacting on productivity of stand at hot-dry valley of Jinshajiang River. It was concluded by the investigation that: the contour trench (40 cm×40 cm), mixted with can increase the field moisture capacity, in accordance, the productivity of stand could bue improved in some degrees. But bearing the weight of soil capability, survival individual plant on unit area was about 525 plant/hm^2. Further-more, introduction of the grade 1 seedling in afforestation could improve survival rate, and facilitate the stand productivity.

土壤含水量是影响金沙江干热河谷造林成败的关键因子，同时也是影响林分生产力的限制性因子，通过试验得出：采用水平沟整地(40cm×40cm)、与多年生小灌木混交，可在一定程度上提高林地土壤含水量，从而使得造林保存率和林分生产能力均有提高，但是受其土壤承载能力的影响，单位面积的保存株数保持在525株/hm^2左右；此外，用Ⅰ级苗木造林，不但可以提高造林保存，对林分的后其生长也有促进作用。

Delineation result based on the improved ant clustering indicated that the study area could be partitioned into two irrigation management zones. Soil field capacity, saturation moisture content and permanent wilting point in Zone I were greater than those in Zone II, which indicated that soil in Zone I had stronger drought resistance than that in Zone II under the same climate conditions. Delineation of irrigation management zones could provide references and data support for site-specified irrigation management.

改进的蚁群聚类分区结果表明，研究区可划分成2个灌溉管理分区，I区土壤的田间持水率、饱和含水率和凋萎含水率均较II区大，表明在相同的气候条件下，I区的土壤耐旱能力较II区强，分区结果可以为精准灌溉的分区管理提供参考依据和数据支持。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
