biomass 中文意思是什麼

Ammonifiers in suzhou creek can not use inorganic nitrogen and carbamide as nitrogen source ; additional carbon source and garbage lixivium have little influence on ammonifiers growth ; high content of salt and low temperature restrain ammonifiers growth ; alkalescent condition has little influence on ammonifiers, but acidic condition restrain ammonifiers growth ; the biomass of ammonifiers are not necessary correlated with the function of ammonifiers, adding glucose with 1g / l content into the water sample obviously promote the growth and function of ammonifiers. physiological groups of bacteria play significant role in the translation and

蘇州河的氨化菌無法利用無機氮和尿素作為氮源；在營養條件充足時添加額外c源和富含有機物的垃圾浸出液對氨化菌的生長基本無影響；高鹽度和低溫抑制氨化菌生長；堿性條件對氨化菌的生長影響不大，酸性條件對氨化菌生長具有抑制作用；氨化菌生物量的消長與轉氨活性之間不存在必然聯系， 1g / l的葡萄糖對蘇州河水樣中氨化菌的數量和轉氨功能具有明顯的促進作用。

The study investigated aboveground growths of caragana korshinskii and artemisia ordosica planted in four modes, revealing that in different planting modes their densities, heights and canopy width and biomasses remained unchanged or tended to decrease slightly ; the young shoots of a. ordosica annually grew in a s - shaped cure and the young shoots of c. korshinskii grew fast in spring and grew slowly or cease to grow from july on ; the biomasses and leaf area indexes of c. korshinskii and a. ordosica annually varied in a double peak curve and there were 8 annual plants that invaded in the four planting modes and formed higher coverage ; the quadrat with only a. ordoska appeared to have obviously lower coverage and biomass that the other three quadrats

摘要對騰格里沙漠東南緣2種人工植被檸條和油篙在4種配置方式下地上部分的生長動態進行了研究，結果表明：不同配置方式下它們的密度、高度、冠幅和生物量基本不變或略微呈下降趨勢；油篙新梢的年生長動態呈s型曲線，檸條新梢春季生長速度較快， 7月份以後生長速度緩慢或基本停止生長；檸條、油篙地上生物量和葉面積指數的年變化均表現為雙峰型， 4種配置方式下共有8種1年生植物人侵，並具有較高的植被蓋度；同其它3個樣地相比，純油篙樣地1年生植物的密度、蓋度和生物量明顯偏低。

And understanding and studying the spectral features and variation rules of geo - targets in the experimental area, raising that it is the basis of geo - targets information collection with imaging spectrometer data to understand spectral features and variation rules of geo - targets, realizing that in a great extent spectral - integrated - form - based classification method can remove the phenomenon of " different spectrum with same objects " resulted from reflection ratio curve translation because of the angle change among sensor, targets and observation direction, and the average and variance images can be introduced to solve the problem of two kinds of geo - target with similar spectral forms and much different values of whole reflection ratio. it is suggested that " red edge " range bands of vegetation, which has close relationship with vegetation cover and biomass, is the main characteristic bands and important basis for careful vegetation classification and quantitative retrieval, and pixel - based derivative spectral analysis is very useful for removing the effects of soil background values and quantitatively retrieving vegetation biomass and cover. the remote sense quantitative retrieval model is developed for main appraisable factors of desertification monitoring assessment with imaging spectrometer data and then the applicability of model is analyzed

研究結果如下：首先針對荒漠化地區的地物特徵，對高光譜數據不同波段的數據質量、波段組合進行了評價，提出了適用於荒漠化監測的基本波段選擇集；初步了解和掌握了研究地區的地物光譜特性及變異規律，進一步明確了掌握地物光譜特徵和變異規律是用成像光譜儀數據提取地物信息的基礎；發現了基於光譜整體形狀的分類方法在很大程度上能夠消除由於傳感器、地物目標觀測方向之間的角度變化引起的反射率曲線整體平移的「同物異譜」現象，對于譜形相似而整體反射率的值相差較大的兩類地物，通過引入均值和方差圖像參與分類得到解決；研究還表明在植被「紅邊」范圍內的波段是進行荒漠化監測的主要特徵波段，這些波段與植被生物量和蓋度都有密切的關系，是開展精細植被分類研究和植被定量反演的重要基礎；像元的導數光譜分析可以消除土壤背景的影響，是進行植被生物量和蓋度定量反演的有力工具；建立了荒漠化監測主要評價因子的定量反演模型，並分析了模型的適用性。
