That is the comprehensive evaluation about the grasses. With SAS Microsoft, Q-type system cluster is done according to the weight of the indices coming from the hierarchy analysis and the grades of the indices. The result is that all the grasses are divided into six types (r0.7) and its almost consistent with the result of comprehensive evaluation but there is slightly difference about red clover, white clover and cocksfoot.

在利用层次分析法得出权重和确定指标分级的基础上，运用SAS统计软件进行数据处理，采用类平均法进行Q型系统聚类，当λ=0.7时，聚类结果与综合性状评定划分的类型基本一致，只在白三叶、红三叶和鸭茅分属类型上有差异。

通过多元逐步回归发现，影响直翅目昆虫种类和数量变化的植被因素有草本植物高度多样性、草本植物种数、菊科优势度、禾本科优势度、其它科优势度。

The city green turf grasses are under seriously stress for the shading of tall buildings, trees and shrubs, and lead to the recession of turf grass, so the author studied for this problem; Taking three cold-season sods as test material, including Festuca rubra Pernille、Poa pratensis Kentucky and Agrostis Regent. Effects of different concentrations of uniconazole (S3307) on shade-tolerance of three turf grasses under shading situation were studied by testing long-term growth and physiological characteristics of them.; After treated with S3307, the contents of chlorophyll and soluble sugar increased, plant height decreased, leaves width and thickness increased. All of these indicated that S3307 can evidently improve shade-tolerance of three turf grasses with different shade-tolerance, the optimal concentration of uniconazole is 100~200 mg/L; The results are very useful and meaningful for improving quality of turfgrasses under shading situation.

高大建筑物、乔木及灌木遮荫会使用于城市绿化的草坪草受到严重胁迫，造成草坪草衰退，针对这一难题进行了研究；以耐荫性不同的冷季型草坪草匍匐紫羊茅派尼、草地早熟禾肯塔基、匍匐翦股颖摄政王为试验材料，研究了不同浓度的外源激素稀效唑(Uniconazole， S3307)处理对3种遮荫草坪草生理及生长变化的长期调控作用；经稀效唑处理，3种草坪草叶片叶绿素含量和可溶性糖含量增高，植株株高变低，叶片变宽、变厚，不同耐荫性草坪草的耐荫能力均得到显著提高，最适的处理浓度范围100~200mg/L；这在生产实际中有重要应用价值，特别对提高受遮荫胁迫的草坪质量具有重要意义。

Results show that water consumptions increase with the increase of mowed heights of turf grasses, which differed for different species. The reducing percentage of water consumptions for the grasses mowed to 5 cm height are 36.78%, 34.02% and 33.54% compared with unmowed grasses. 34.78% of average water consumption is expected to be consumed.

研究结果表明：草坪草的耗水量均随修剪留茬高度增加而增加，不同草种间存在差异。3种草坪草修剪留茬高度为5 cm时较不修剪耗水量减少36.78%、34.02%、33.54%，平均减少耗水量34.78%。

Result With young elm forest-pumpkin strip intercropping, since the branch tendril covered the gap between pumpkin planting-ditches and elm forest land, the soil moisture was remarkably increased. And the water use efficiency under intercropping increased by 23.7%-163.3% compared with the sole cropping. Elm-pumpkin strip intercropping changed the sequential succession trend of the grasses growing in the gap of the pumpkin planting-ditch, annual grasses became the dominant vegetation, and the feeding nutrient matter content and yield of the annual grasses increased significantly.

榆树幼林与南瓜间作后，瓜蔓覆盖地面，显著提高了南瓜行间和榆树林地的土壤水分含量，林－瓜间作地水分的利用效率较单作提高了23.7%~163.3%；间作改变了南瓜行间杂草群落自然演替的方向，一年生杂草成为优势物种，其饲用营养物质的含量和产量较林带间杂草显著提高。

In wetter habitats, forbs were more abundant and accounted for the majority of aboveground biomass, whereas grasses became more important in dryer habitats. Shrubs and sub-shrubs increased with decreasing soil water availability and their relative biomass rapidly increased in degraded steppe and sand dune; perennial grasses had significantly higherδ〓C values than other PFGs; the δ〓C values of perennial grasses and forbs increased with decreasing soil water availability, while those of shrubs/sub-shrubs showed an inverse trend.

在较湿润生境，多年生杂类草更加丰富并构成了群落地上生物量的绝大部分；而在较干旱生境下，多年生禾草在群落中起更重要的作用；随着土壤含水量下降，灌木和半灌木逐渐增多，且在退化草地和沙地中其相对生物量迅速增加；多年生禾草δ〓C值显著高于其它功能群；随着土壤水分可利用性降低，多年生禾草和杂类草的δ〓C值表现出增加的趋势，而灌木/半灌木则表现出相反的趋势。

To improve the water efficiency of turf grasses, the effects of mowed heights(5, 10, 15 cm and without mowing) of three kinds of turf grasses (Poa pratensis, Festuca arundinacea, Lolium perenne) on water consumptions were studied using portable lysimeters under full water supply conditions. Water consumptions of the three kinds of turf grasses were estimated from experimental data with water balance model.

为了研究草坪修剪管理的节水效果，采用小型排水式蒸渗仪，通过田间实验研究了充分供水条件下3种草坪草不同修剪高度(留茬高度：5、10、15 cm和不修剪)处理对耗水量的影响，并根据水量平衡原理计算得到了3种草坪草的耗水量。
