Based on the investigation and analysis of the Cupressus funebris seed orchard at Laoshan Island in the Qiandao Lake, Zhejiang province, the ecological characteristics of the male cone, female cone and pollen have been studied.

本文以浙江省千岛湖姥山林场柏木种子园为对象，对柏木球花及花粉的生态学特性进行了研究结果表明，柏木的雌雄球花在树冠中呈成层分布；降雨时，雄球花对花粉具有保护功能；柏木花粉体积小，重量轻，花粉量大，花粉的散发受气温、风力、相对湿度和气压的综合影响，其中气温是主导因子，风左右着花粉的传播，降雨加速花粉的沉降。

Pattern of change of time of two ground time is roughly same also, sichuan at the beginning of time of ~60 of 50 time end warmer, end of time of the ~90 at the beginning of 60 time slants cold, air temperature is apparently elevatory since 90 time end and strength is greater; Chongqing end of time of ~60 of 50 time end is warmer, air temperature change and Sichuan province are basic and identical after 70 time.

With statistical method,the high temperature in all area of Shandong province is analyzed.The results indicate that there is apparent interdecadal variation for the estival hot days and the extreme high te...

利用统计方法分析山东省各地高温多年变化特征，发现夏季高温日数和极端最高气温均存在明显的年代际变化，且东西部变化不尽相同；在60年代末70年代初全省夏季极端最高气温发生了一次转折性变化。

The authors collect and process the discharge rate data of Hongshanzui hygrometric station from 1956 to 2003,day-to-day precipitation and air temperature data of Shihezi City from 1953 to 2003.The correlation curves of the three variables are constructed.And the functions of annual precipitation and mean annual air temperature,to mean annual flow rate of Manas River are analyzed.

笔者对玛纳斯河出山口红山嘴水文站的流量资料(1956—2003年)及石河子市的逐日降水和气温资料(1953—2003年)进行分析，介绍各自变化特点并建立它们之间的年均变化对比曲线，分析年均流量与年降水量和年均气温的关系。

The comparative study on vegetation background survey of the stationsand the comparison on level of phytocoenology on zonal habitats indicates thatthe diminishment of the numbers of families,genus and species,compositionof life types,diversity of communities and habitats,;and the increscence in theproportion of photosynthesis functional groups of C3/C4 plant,richness ofspecies,density of tussock and tiller,diversity of species,evenness,leaf areaindex,leaf area duration,dry matter production of communities alongside thelatitude increasing and the temperature decreasing;and the dynamic curve ofthe community productivity also tend to steadily increase along with thetemperature going up and the heat accumulation gradually in moderate-temperate steppe station from violent fluctuation along with seasonal badly-distribution of precipitation in warm-temperature steppe station;manifestingthat transformable tendency of productivity pattern of the community from morevigorous net assimilation,sparser and higher crops stricture of tussock and tiller,and possession on more resources by less species inclined to thicker in densityof crops,superior effectiveness of multi-leaves and pattern of multi-speciesresource sharing,reflecting that bigger disparity of the vegetationcharacteristics and the style of the community growth in the two differentthermal-type steppe stations owing to background of natural-historicenvironment and combination of water and heat.

内蒙古草原区两个不同热量型研究站点植被本底调查和显域地境群落学水平的比较研究表明：随纬度增加和气温降低，植物科、属、种的数目，生活型组成，群落类型和生境类型的多样性均趋于减少，而C3/C4光合功能群比值和群落的物种丰富度，株丛密度，物种多样性，群落均匀度，叶面积指数，叶面积持续时间和群落干物质生产能力均趋于增加，群落生产力动态曲线从随天然降水的季节分布不均而剧烈波动趋向于随气温逐渐升高和热量逐步积累而稳定增长，显示出两站点植物群落从较为旺盛的群体净同化作用、较为稀疏高大的群体结构和少数物种占有较多群落资源的生产力格局向较高的群体密度、优良的多叶性能和多物种资源共享的群落生产力格局转变，反映出在内蒙古草原区不同的自然历史环境背景和不同的温度条件及其水热组合状况影响下，两个不同热量型草原站点植被性质的分异特征和显域地境群落生长模式的较大差别。

Leaves structure of different provenances vary greatly in the thickness of keratoid layer, epidermal layer, palisade mesophyll, spongy mesophyll and the stomatal density. The CTR value is negatively related to the temperature of growing site and the SR value is positively related to it, which is an evidence for the plant to adapt to the environment.

西南桦不同种源叶片的结构在角质层、表皮层、栅栏组织、海绵组织厚度以及气孔密度等方面都发生了较大的变异，叶片的紧密度与种源地气温呈负相关，疏松度与气温呈正相关，这是植物对环境适应的表现。

The order of the effect of the climatic factors on the increment of Larix leptolepis was The precipitation of last summer, 10 cm groud temperature of Spring, the relative humidity from September to October in last year,≥10℃ accumulative air temperature ,10 cm groud temperature from September to October in last year, sunligh hours, relative moisruer of Februry, precipitation of November, the average temperature from April to May last year, the average temperature of last Winter.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
