Based on the above conclusions about anti - erosive vegetation structure, the paper expounds the implication of anti - erosive vegetation by pointing out the fault of its current definitions, and it is considered that anti - erosive vegetation should aim at protecting soil from erosion and fixing active sands in the eroded areas, ground space fully occupied by plants, in general with close structure, especially with outstanding coverage close to ground by organic matter ( litter and / or biomass )
在上述結論的基礎上，本文通過指出現有防蝕植被定義的缺陷，論述了其涵義，認為防蝕植被應當是在侵蝕地區，以防止土壤侵蝕或以固沙為目的，植物充分佔據地面空間，一般具緊密結構，或者顯著具有有機體（枯落物以及生物量）貼地面覆蓋特徵的植被。 -

摘要利用時空替代原理，選取灕江流域紅壤區退化生態系統恢復過程中具有代表性的草叢、灌叢、針葉林、針闊混交林、常綠闊葉林5個階段作為演替序列，研究自然恢復過程中各演替階段的植被結構動態和生物量變化。 -
The community productivity, structure and succession are significantly influenced by global climate changes. this study focused on soil respiration rate of stipa baicalensis grassland by using dynamic infrared gas absorbed method. we analyzed diurnal pattern of soil respiration rate and the influences of surface soil temperature and water content for this parameter, then compared the differences between day and night soil respiration rates, and explored the correlations between aboveground and underground biomass with the soil respiration
溫帶的半乾旱、半濕潤區草甸草原屬于過渡氣候影響下形成的植被類型，對環境氣候條件變化十分敏感，為了揭示半乾旱、半濕潤區草甸草原生態系統土壤碳素釋放規律及其對主要環境因子的響應，本研究採用動態室紅外氣體吸收法測定松嫩草甸草原典型群落? ?貝加爾針茅群落土壤呼吸速率，分析了土壤呼吸速率日變化規律及表層土壤溫度和含水量對土壤呼吸速率日變化的影響，比較了土壤呼吸速率的晝夜差異，探討了地上生物量和地下生物量與土壤呼吸速率之間的相關關系。 -
This paper introduce, on the basis of consulting a lot of data, during to the question of shortage of energy source in the world and adjusting to structure of energy source under the new condition of 21 century and the question of tar during the crop stacks - based biomass gasification
本課題是在查閱大量資料的基礎上，針對世界范圍內能源缺乏問題和21世紀新形勢下的能源結構調整問題以及生物質秸稈氣化過程中產生的焦油等問題而提出的。通過查詢可知目前國內外還沒有人涉足這方面的研究。 -
It can not only relieve the demand press of power fuel and improve the using efficiency of biomass energy in china rural area, but also can improve the structure of china energy. the research was conducted according to this purpose
不僅有利於改善我國目前廣大農村地區商品能源緊張的局面，提高農村生物質能的利用效率，為農村地區因地制宜地提供清潔方便能源，而且有利於改善我國目前以化石燃料為主的能源生產和消費結構。 -
The ecological study of macrofauna was conducted on four typical sampling stations selected in the northern muddy bottom area of jiaozhou bay, estuary of dagu river, culturing and nearby area in hangdao in mar., jun., aug. and dec., 2002. abundance and biomass of macrofauna were investigated by quantitative study. the macrobenthic community structure and biodiversity were analyzed through multivariate statistic analysis
本研究分別在膠州灣北部軟底區、大沽河口、黃島養殖區及養殖區鄰域選取四個典型站位，於2002年3月、 6月、 8月和12月野外采樣，對大型底棲動物進行了定量研究，採用多元統計方法分析了群落結構和生物多樣性，探討了底棲生物群落與環境因子的關系；用豐度和生物量比較曲線法分析大型底棲生物群落對自然和人為擾動產生的響應。 -
Studies on the community structure and biomass of summer birds in wutong mountain, shenzhen
深圳梧桐山夏季鳥類群落結構及生物量的研究 -
Both the grazing frequency and different number of herd influence the species composition of bird community, the bird species increasing following the decreasing of grazing frequency ; and the biomass decreasing following the increasing of grazing frequency, the bird species increasing following the decreasing of the number of herd ; the biomass of bird community decreasing following the increasing of the number of herd the grazing disturbance influences bird community structure by two ways : one way is that grazing disturbance influences bird community directly ; the another way is that grazing disturbance influences bird community indirectly by changing vegetation structure and habitat structure
放牧頻次和不同數量的牧群影響鳥類群落種類組成，隨著放牧頻次的減少，鳥類群落組成的物種數增加；隨著放牧頻次的增加，鳥類群落的生物量呈現出顯著的遞減。隨牧群數量的減少鳥類群落組成的物種數減少；隨著牧群數量的增加，鳥類群落的生物量呈現出遞減的趨勢。放牧干擾對鳥類群落組成影響的原因有兩方面：一是牧群的直接干擾；另一個原因是放牧影響植被結構和生境結構的變化，間接對鳥類產生影響。
