We analyzed and discussed the characteristics of cycle of carbon and water,and after having obtained important physiological parameters based on field experiment,a process-based, multilayer two-leaf model which calculates energy and material cycle separately for sunlit and shaded leaves was developed,then characteristic of CO_2 fluxes above the canopy was simulated.The main results are as follows:1.Characteristics of carbon and water cycle in the relationship of leaf photosynthesis -stomatal conductance-transpiration.

本研究以冬小麦为研究对象，利用LI-6400R光合—蒸腾测量系统、LI-6400-09土壤呼吸室和禹城生态试验站涡度相关系统等高精度仪器设备，对2007年和2008年小麦拔节至乳熟期间涉及碳、水循环过程的叶片光合—蒸腾作用、土壤呼吸作用及相关农田气象要素和植被特征进行了野外试验测定和分析，在试验观测基础上提取了重要生理参数，建立了基于过程的农田与大气间物质输送和能量交换的多层—双叶模型，并对2008年试验期间冠层上方碳通量特征进行了模拟，试验分析和模拟的主要结论如下：1。

The paper introduces the latest development and application in the production of engineering survey technology. GPS allocation technology and the combination of GPS and total station have been widely used in plane surveying of control survey. Electron distance trigonometric leveling can replace third and fourth-order spirit leveling in vertical survey. Data collection, processing and drawing by total station has achieved automation and integration in topographic survey, etc.

随着工程测量技术的发展，控制测量中平面测量已广泛地采用了GPS定位技术、GPS与全站仪相结合的技术，高程测量中电子测距三角高程能代替三、四等几何水准测量；地形图测绘中，实现了全站仪从野外数据采集、处理到绘图过程的自动化和一体化；摄影测量和高分辨率遥感技术在大比例尺地形测图中的应用等。

CANBERRA - Australian firefighters are hoping for a barbecue, snow and a few hours sleep on Christmas Day as bushfires continue to blacken the country's southeast.

据路透社12月21日报道，澳大利亚东南部地区的森林大火最近一直烧个不停，而对那些始终奋战在扑火最前沿的消防员来说，他们眼下最希望看到的情景就是几天后能迎来一个雪花飞舞的圣诞节，这样便可以借机吃上一顿野外烧烤，然后抓紧时间睡上几个小时。

On the basis of field investigation about the arbor, shrub and steppe communities in Wuqi county, the authors quantitatively analyzed the vegetation recovery and the relationship between vegetation recovery and soil erosion.

中文摘要：在对吴旗县乔木林、灌木林和草原群落野外调查的基础上，对其植被恢复及植被恢复与水土流失的关系进行了定量分析，结果表明，在吴旗县这样的自然地理条件下，通过退耕还林、封山禁牧，植被完全可以得到恢复，完全可以控制水土流失的发生。

Based on the field investigation in Aug 2001 and Aug 2002, digital China Vegetation Map in 2001 and Qinghai-Xizang Plateau Vegetation Regionalization Map in 1996, vegetation characteristic along two sides of Qinghai-Xizang highway and railway is studied in this article Meanwhile, the impacts of Qinghai-Xizang highway and railway constructions on the ecosystems are analyzed using ARCVIEW、ARC/INFO and PATCH ANALYSIS It was found that:(1) Qinghai-Xizang highway and railway span 9 altitudes,12 longitudes and 6 natural regions (East Qinghai and Qilian mountain steppe region, Chaidamu mountain desert region, South Qinghai alpine meadow steppe region, Qiangtang alpine steppe region, Guoluonaqu alpine scrub meadow region and South Xizang mountain shrub steppe region);(2) the constructions of Qinghai-Xizang highway and railway destroyed natural vegetation and landscape, especially in 50m-wide buffer regions along both sides of the roads, it was estimated that the Primary Productivity deceased by about 30504.62t/a and the gross biomass deceased by 432919.25～

：根据2001-08和2002-08月野外调查数据及2001年1∶100万中国植被图、1996年1∶400万青藏高原植被区划图和2000年青藏铁路沿线自然保护区分布及功能区界调整图，以青藏公路铁路沿线植被生态系统为研究对象，运用ARCVIEW和ARC/INFO软件研究青藏公路铁路建设对沿线生态系统结构的影响，结论如下：①青藏公路铁路南北跨越9个纬度，东西跨越12个经度，共穿越青东祁连山地草原地带、柴达木山地荒漠地带、青南高寒草甸草原地带、羌塘高寒草原地带、果洛那曲高寒灌丛草甸地带和藏南山地灌丛草原地带6个自然区，对植被类型的统计结果显示了地带性。②青藏公路铁路的建设对生态系统产生直接的切割，使景观更加破碎。
