Mankind appropriates about a quarter of what is known as the net primary production of the earth ( this is the plant tissue created by photosynthesis ) ? a lot , but hardly near the point of exhaustion 人類(lèi)消耗了1 / 4的被稱作地球主要凈產(chǎn)出的產(chǎn)品(由光和作用產(chǎn)生的植物組織) ,雖然很多,但離耗盡還遠(yuǎn)得很。
The simulated results of net primary production ( npp ) are similar to other ' s study . the annual , seasonal and daily change of npp can reflect the physiological characteristic of vegetation growing very well and has close relationship with climatological factors 年npp的模擬結(jié)果與國(guó)內(nèi)的一些其它類(lèi)似研究結(jié)果接近, npp的模擬結(jié)果能較好地反映出植被生長(zhǎng)的生理特點(diǎn)npp的月變化、日變化及年際變化對(duì)氣候因子有不同的響應(yīng)。
The net primary production of chinese terrestrial vegetation during 19821999 excluding 1994 because of missing data was estimated , and its spatio - temporal patterns were explored , based on the casa carnegie - ames - stanford approach model and using remote sensing imagery noaa avhrr and land spatial data of vegetation , climate , soil and solar radiation 基于地理信息系統(tǒng)和衛(wèi)星遙感技術(shù),利用植被氣候和土壤等地面空間數(shù)據(jù),應(yīng)用casa模型估算了19821999除1994年間我國(guó)植被年凈第一性生產(chǎn)量及其時(shí)空變化。結(jié)果表明: 18年間我國(guó)植被凈第一性生產(chǎn)量呈增加趨勢(shì),平均增加速率為0 . 024pgca
In one side , the study may make the simulating model of climatology and land - biosphere more perfect , in the other side , the study will help to discover the real action of vegetation in the global carbon circle , which gives the more scientific method to estimate accurately biomass and net primary production ( npp ) of ecosystem and how much carbon in atmosphere absorbed by vegetation , to predict the possible impact of global climate change on terrestrial ecosystems , and to make scientific strategies for the global change 一方面可以為進(jìn)一步建立更完善的模擬氣候與陸地生物圈之間關(guān)系的數(shù)值模式奠定基礎(chǔ),另一方面可為探索植被在全球碳循環(huán)中的具體作用,正確地評(píng)估和預(yù)測(cè)全球氣候變化對(duì)生態(tài)環(huán)境的可能影響,制定相應(yīng)的政策提供科學(xué)依據(jù)。本文以寒溫帶落葉針葉林區(qū)為重點(diǎn)來(lái)進(jìn)行試驗(yàn)?zāi)M,研究植被對(duì)氣候強(qiáng)迫響應(yīng)的有效途徑。
