The human being is not only a component of biosphere which subjects the regulation of the natural process of the earth , but also has more active function in the earth system which is unique and different from other components of biosphere 同時,隨著科學技術的高速發展,憑借高度發達的智力和想象力,人類已經能夠完整地理解地球系統的整體行為。

The crc for greenhouse accounting is researching and developing simple , accurate and cost - effective techniques that account for the presence and behaviour of carbon ( c ) in our soils and vegetation biosphere 描述:澳大利亞溫室氣體釋放統計合作研究中心通過研究和發展簡易、精確和富有成效的技術檢測統計在土壤和植被生存范圍氣體含碳量及活性。

Dynamics of soil no3 - - n and its response to n additions in the major forests ( pine , mixed and monsoon evergreen broadleaf forests ) of dinghushan biosphere reserve were studied by using ion - exchange resin bags method 用離子交換樹脂袋法,研究了鼎湖山三種森林(馬尾松林、馬尾松針葉闊葉混交林和季風常綠闊葉林)土壤硝態氮對外加氮的響應特征。

A guided walking tour of the grounds includes an informative greenhouse exhibit of plants that have been useful to humans as well as detailed information on the materials used in biosphere 2 and its construction 有導游帶領的對這個基地的徒步旅游包括參觀對人類有益的溫室植物展覽和了解用在生物圈2號的材料及其建造的詳細情況。

This somber prediction comes out of the latest findings of the large scale biosphere / atmosphere experiment in amazonia , the most ambitious field project ever done in a tropical ecosystem 亞馬遜地區大尺度生物圈與大氣圈試驗是目前在熱帶生態系進行的最大型研究計畫,科學家根據他們最新的研究結果,做出了上述令人擔憂的預測。

The legislation of property right is the focus of law today , and one important content in the future civil code . forest resource is important natural resource and significant to the biosphere 我國在《森林法》中已確立了森林資源的國家所有制,并以此為理論核心構建了森林資源的產權取得及登記制度。

But the facts are plain and uncontestable : the biosphere is finite , nongrowing , closed ( except for the constant input of solar energy ) , and constrained by the laws of thermodynamics 然而,事實清楚擺在眼前:生物圈絕對是有限的、無法成長的、封閉的(太陽能的持續輸入除外) ,而且受到熱力學的限制。

We should face these present issues , regard urban ecosystem as ingredient of the biosphere , take certain precautions , finally , realize the harmonious development between biodiversity conservation and urban ecosystem 本文從幾個方面探討了生物多樣性保護與城市生態系統的關系及協調發展等問題。

“ our results raise the possibility that a biosphere could have arisen on earth 400 million years earlier than is now thought , “ harrison said . “ but it ' s not a smoking gun . “我們的結果提高了生物圈比我們現在想象的更早的4億年出現在地球上的可能性, “哈里森說。 “但它不是一只煙槍“ 。

Based on meteorological data recorded for about 3 - 5 years in four forests at different elevation in dinghushan biosphere reserve , the differences in forest temperature and moisture were analyzed 摘要利用3 - 5年的觀測數據,分析了鼎湖山4種不同海拔高度森林溫濕度的差異及其原因。

In keeping with the biosphere reserve model , it will promote greater community involvement and intergovernmental coordination in managing nature reserves 按照生物圈保護區模型,本項目還將進一步擴大社區的參與以及加強在自然保護區管理的過程中政府間的協調作用。

For many of the 180 , 000 or so annual visitors , part of biosphere 2 ' s allure lies in its first mission as an experimental habitat for space travelers 對于每年大約18萬中的許多游客來說,生物圈2號的吸引力在于它作為太空旅游者的一個實驗性的生活環境的首要使命。

Because biosphere 2 is a closed system , rainfall and aimospheric makeup can be regulated and measured , a1lowng scientists to conduct controlled experiments 因為生物圈2號是一個封閉的系統,所以降雨和大氣結構都可以被調節和測量,以利于科學家做控制性實驗。

The biosphere , a thin shell that encapsulates the earth , is made up of the atmosphere and lithosphere adjacent to the surface of the earth , together with the hydrosphere 生物圈就像一層包裹著地球的薄的貝殼,它由大氣圈、水圈以及地表附近的巖石圈組成。
