落叶

You might have thought it was summer except that the whole forest was strewn with fallen leaves－some yellow as saffron, some red as wine, some the color of gold and some of mixed col

要不是整个森林充满着落叶你可能会以为这是夏季。一些落叶是程黄色的，一些是酒红色的，还有金黄色的，另一些是混合的颜色。

You might have thought it was summer except that the whole forest was strewn with fallen leaves－some yellow as saffron, some red as wine, some the color of gold and so

这些落叶有些在白天，有些在夜里被雨打落，被风吹落，如今它们在森林的地面上形成了一条厚厚的落叶毯子。

The defoliates increase gradually because of the autumn, please make sureyour balcony floor drain work properly, check whether it has stuck by leavessoaking as a result of the rain. If you need help from the management company,please contact the management service center or your seneschal.

随着秋季的来临，落叶逐渐增多，麓山物业特别温馨提示：请阁下注意检查阳台上的地漏是否有落叶等杂物堵塞，同时排水孔若有污垢也需及时清理干净，以免下雨造成浸水给阁下带来不便，若需物业协助，请与物业客服中心或组团管家联系。

There were only 94 vascular plant species, belonging to 50 family and 75 genera. The dominant species in the communities were deciduous broadleaf species Liquidambar formosana, Robinia pseudoacacia, Ailanthus altissima, Acer buergerianum, and Celtis sinensis, evergreen broadleaf species Cinnamomum camphora and Elaeocarpus glabripetalus, and Phyllostachys heterocycla. Robinia pseudoacacia+Cinnamomum camphora community had the highest Shannon-Wiener index (1757) and Phyllostachys heterocycla+Acer buergerianum community had the highest Simpson index (0163), but no consistency was observed between the curves of H and D. For vertical structure, most communities had no significant understory stratification.

结果表明：辰山植物区系以泛热带和北温带占优势，具有典型亚热带和温带成分交汇和南北植物分布交错特征；但保育区内种类单一，维管束植物仅有49科69属94种；主要群落是以枫香、刺槐、臭椿、三角枫和朴树等为优势树种的落叶阔叶林，以香樟和秃瓣杜英等为优势树种的常绿阔叶林，以及毛竹林；物种多样性普遍较低，Shannon-Wiener多样性指数最高为刺槐+香樟群落（1.757），Simpson均匀度指数最高值为毛竹+三角枫群落（0.163）；多样性指数曲线和均匀度指数曲线不具有一致性的变化趋势；多数群落垂直结构中无明显林下分层现象；演替前期的落叶乔木种群后续个体不足。

Leaves evergreen, deciduous or semideciduous, alternate, sometimes clustered at stem apex; margin entire, very rarely crenulate, abaxial indumentum sometimes with a pellicle (a thin skinlike layer on the surface).

灌木或乔木陆生的或附生，常绿的叶，落叶或半落叶，互生，有时在茎先端的簇生；边缘全缘，极少具细圆齿，背面毛被有时具一表膜。

Water holding capacity of litter layer was stronger than that of moss,indicating that forest litter layer played a much more important role in headwater conservation.

枯枝落叶层持水性能优于苔藓，说明枯枝落叶层在森林的水源涵养方面发挥了更为重要的作用。

During thawing period, its soil water changes as season changes (the dynamic rule of soil water has the important relation of the season): from June to July the quality-moisture content of soil water gradually increases and reaches the highest, and from July to August it begins to decreases. The range of the quality-moisture content of the ground litter and humus layer is lower than the illuvial horizon whose quality-moisture content is gradually increasing in this thawing season.

在土壤冻土融化期，草类落叶松林土壤水分存在明显的季节性变化，土壤枯枝落叶层、腐殖质层质量含水量比淀积层质量含水量变化幅度大；6～7月份土壤含水量逐渐增加，达到最高；8月份以后土壤含水量开始降低；土壤淀积层质量含水量保持逐渐上升趋势；坡顶土壤质量含水量明显小于坡底土壤质量含水量。

These six species are contrasted with three different phenological types, i.e., an evergreen, Cyclobalanopsis helferiana, two winter-deciduous, Buchanania latifolia and Symplocos racemosa, and three drought-deciduous species, Terminthia paniculata, Wendlandia tinctoria and Woodfordia fruticosa.

这6种植物包括1种常绿植物毛枝青冈， 2种冷凉季落叶( WD， winter-deciduous)植物天干果和珠仔树，3种干热季落叶(DD， drought-deciduous)植物三叶漆、红皮水锦树和虾子花。

The preferred habitat types of Cabot's tragopan in each season were: evergreen-deciduous forest and the broadleaf strips in spring; the broadleaf strips and shrubs in summer and evergreen-deciduous forest and shrubs in autumn; the habitat selected in winter was the same as that in spring but were more relied on by the birds.

黄腹角雉所偏好的栖息地类型，在春季为常绿阔叶--落叶混交林和人工针叶林中的阔叶林条带；夏季为阔叶林条带和灌草丛；秋季为常绿阔叶--落叶混交林和灌草丛；冬季与春季相同，但对这两种类型栖息地的依赖性比春季更强。

The results indicated that the growth of 3-year-old Prunus salicina was significantly higher than that of the other species, such as 139.1% and 153.7% higher than Toona sinensis and Juglans regia in height growth, respectively. The maximum percentage of DBH more than 1.0 cm was 91.9% for P. salicina. Next were 49.5% and 48.8% for Ulmus pumila and Pteroceltis tatarinowii, respectively. The contents of total N, total P and total K ranged from 1.36% to 2.52% in the leaves of testing species. The highest content of total N and total P was found in the leaves of Catalpa bungei, while the highest content of total K was observed in P. saltcina leaves. The results indicated that P. salicina, P. tatarinowii, U. pumila had well adaptability on the Karst area both in the growth status and the improvement to the soil with the fallen leaf.

结果表明：(1)3年生冰脆李的生长量明显优于其他树种，其高生长比香椿、核桃分别大139.1%和153.7%；植株胸径大于等于1.0 cm株数的百分比以冰脆李最高达到91.9%，其次是榆树和青檀，分别是49.5%和48.8%；(2)8个树种落叶的全N、全P和全K的总含量变动为1.36%~2.52%，其中全N、全P含量以滇楸最高，全K含量以冰脆李最大；(3)从各树种落叶前后各元素含量及其转移情况看，冰脆李、青檀表现出对大部分营养元素具有较高的循环利用养分或保持养分的能力，而香椿及刺槐相对较弱。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
