Seven plots selected from wanglang reserve were distributed in different types of forest and at different altitude, and different plot has different microclimate. soil property, microbial population, soil nutrient content of forest soil were determined in wanglang natural reserve, from may to october 2002 to july 2003, the ecological distribution of three main groups, bacteria, actinomycete and fungi were determined in the forest soils by the cell enumeration methods. six kinds of physiological groups, including ammoniation bacteria, nitrification bacteria, nitrosification bacteria, aerobic autogenesis azotobacter, aerobic cellulose - decomposing bacteria and anaerobic cellulose - decomposing bacteria were enumerated by the most - probable number ( mpn )
2001年10月在王朗自然保護區內設立了3個定位研究樣地和4個臨時樣地,通過多次現場采樣與室內實驗分析,測定了白樺林、岷江冷杉林、紫果雲杉林、繡線菊-羊茅群落、羊茅群落及高山柳灌木叢等6種不同植物群落內土壤微生物三大類群數量、功能微生物數量、土壤養分,並在固定樣地內使用埋袋法進行了三個埋藏深度的凋落物分解袋試驗,初步研究了枝條、闊葉、針葉等凋落物組分在不同分解階段所含養分的動態變化。The growth dynamics of tree basal area of form. taxus chinensis var. mairei population in different altitude were discussed using the liu - logistic model, and the results showed that the altutide of 790 meters is more suitable to the survive of form. toms chinensis var. mairei population than 990 meters. plot sampling was selected and dynamic analysis was used to study the height structure of taxus chinensis var. mairei population, and the quadrate picture of height structure and the curve of survival rate were drew
運用改進模型對南方紅豆杉種群在不同海拔梯度的種群優勢度增長進行了探討,表明海拔790m處的南方紅豆杉具有較大的環境容納量,但增長速度不快,海拔990m處的南方紅豆杉種群環境容納量不高,但具有較大的增長速度,這可能與群落的發育階段不同有關,兩地海拔均為南方紅豆杉適宜的生長海拔高度,相比而言,海拔790m的珍稀瀕危植物南方紅豆杉種群數量特徵的研究高度更宜於南方紅豆杉種群的生長。With the increase of abandoned time, perennial plants increased, the function communities were richer, p diversity index in two communities reduced with abandoned interval, but the vegetation restoration was slow, the land abandoned for 30 years have not got to climax community
隨撂荒年限的增加,多年生植物的種類和數量逐漸增加,植物群落功能群構成逐漸豐富,群落間多樣性指數隨撂荒時間間隔的增大而逐漸減小。但植被恢復緩慢,撂荒30年仍未達到頂極群落階段。V ) occupying space and covering ground should be served as the main strategy in early stage of vegetation restoration, which would enable the community coverage to rehabilitate rapidly. in mid - stage, due to the change of light environment and the species substitution, component adjustment should be chose as the main strategy
5 )植被恢復的策略是早期階段以搶占空間、覆蓋地面的對策為主,群落蓋度恢復很快;中期階段,林內光照環境改變,物種替代,恢復對策以物種組成成分的調整為主;後期則是生物量積累與組成結構調整並重。The structures and dynamic changes of the artifical sand - fixing vegetation were studied based on the follow views : components of vegetation community, plant diversity, life - forms of vegetation, trends of plant growth, characteristics of the vertical and horizontal structure of vegetation, relationship between the vegetation community and environment ( including soil moisture temperature etc. ), relationship between the vegetation community and characteristics of plant physiological activities. some results were showed as follow : 1. components, diversity and life style of artificial vegetation in shapotou region the marked changes of artificial vegetation have taken place during more than 40 years, since the establishment of sand - fixing vegetation
本文以騰格里沙漠東南緣寧夏中衛縣沙坡頭地區人工固沙植被作為研究對象,採用傳統生態學的野外調查方法,從植被群落的組成、多樣性、生活型、群落生長動態、垂直結構特徵、水平結構特徵、群落結構與周圍環境(土壤含水量、溫度)相互關系及其與植物自身生理生態適應特徵關系等多個角度研究了人工植被群落的結構及其動態變化,取得了如下研究結果: 1 、植被群落組成、多樣性及生活型:沙坡頭地區人工植被經過近50年的演變,從流動沙丘到固定沙地,沙地植被的動態變化經歷了從人工植被到人工?自然植被的轉變,從人工植被建立初期的少數幾種引種植物到現有30多種植物,隨著固定沙地時間的延長,植物種類日趨豐富,並且人工植被在15 25年、 40 50年兩個階段,物種的周轉速率最大,即群落結構變化最大。On the basis of substituting space for time, communities dynamic characteristics including composition and structure, species diversity, population niche, soil nutrient content were investigated
本文採用以「空間代替時間」的方法對各個恢復階段植被群落的動態特徵,包括:物種組成結構、物種多樣性、種群生態位、土壤營養元素含量變化的特徵進行了研究。A stage in ecological development in which a community of organisms, especially plants, is stable and capable of perpetuating itself
頂極群落,演替頂極生態發展的一個階段,在此階段一群有機體(尤指植物)能保持自身的穩定及永存Bothriochloa ischaemumis the dominant species in all the plots, while the other species flourish or decline successionally at different grazing stages
在不同的利用階段,白羊草種群都是優勢種,而其他植物種則呈現不同的趨勢。Climax the final community in a succession of natural plant communities in one area under a particular set of conditions
演替頂級:在一定條件下,自然植物群落的最終演替階段。Lant variety ? is a plant grouping within a single botanical taxon of the lowest known rank, which grouping, irrespective of whether the conditions for the grant of a breeder right are fully satisfied
植物品種系指一種屬于已知最低階之單一植物分類群范圍內的植物分組,不論是否完全符合育種家權利之授與條件,該分類群可以是:Based on long - term site studies and all - around investigation, we ascertained six subpopulations of lilium isingtauense at different altitude, applied gps, gis to make certain the orientation of individuals and mensurated their heights in each subpopulation, and estimated the age class of lilium tsingtauense. at same time some environment factors have been test with which the species growth and development have relationship. lilium tsingtauense, which mainly distributes in mountain lao, is an endemic, rare and endangered plant in china
我們選擇青島百合作為範例開展植物復合種群的研究,在長期全面調查的基礎上,選擇典型分佈區域設立了研究樣帶,確定了青島百合復合種群的六個局部種群,並圍繞個體生長階段進行了長期的跟蹤調查,應用gps對每株植物的空間位置進行了定位,測定了植株的高度,估測了植株的年齡等,在此基礎上將取得的調查資料與地理信息系統( gis )分析工具相結合,對青島百合復合種群進行了較為全面的研究。分享友人
