  1. The research result is following : the annual species richness index of studied forest plant community averaged 64. 688, the species diversity index was 2. 982. the proportion of every functional group of forest plant community is : herbaceous layer ( average is 68. 89 % ) > tall tree layer ( average is 15. 266 % ) > shrub layer. ( average is 15. 845 % ) the proportion of every functional group in forest insect communities is remarkably different, and the order of the proportion is herbivorous insect group ( average 0. 729 ) > predatory natural enemy insect group ( average 0. 136 ) > parasitical insect group ( average 0. 135 ). with seasonal change, the proportion of herbivorous and predatory insect group decreased obviously, while that of parasitical insect group increased on average by 147 %

    研究結果如下：森林植物群落種的全年物種豐富度指數平均為64 . 688種，多樣性指數為2 . 982森林植物群落內各功能類群物種所佔比重依次為：草本層（平均為68 . 89 ） >喬木層（平均為15 . 266 ）灌木層（平均為15 . 845 ） 。森林昆蟲群落中，全年各功能類群所佔比重以植食性昆蟲類群為最大，平均佔0 . 729 ；捕食性昆蟲類群次之，平均佔0 . 136 ；寄生性天敵類群為最小，平均為0 . 135 。
  2. Through investigating their index of growth and soil water content from april to october, observing their species composition in july and above - ground biomass in september, measuring seasonal changes of plant moisture stress, net photosynthesis rate, transpiration rate of s. viciifolia and hance, after analyzing all kind of data, the following conclusions can be drawn : 1

    主要結論如下： 1 、狼牙刺的株高在1 . 50m左右、冠幅約2 . 0 2 . 0m 、平均分枝數約為4 . 45 。不同立地條件下，狼牙刺覆蓋度均在50以上，加上林下草灌層在生長旺期總蓋度均能達到70以上。
  3. 2. the range of soil co2 concentration varied with soil temperature is not the same for the soil layer and its characters and different vegetation : the varied range of topsoil is higher than that of deep soil at testing woodland ; the varied range of soil layer ( - 20cm ) is the highest than that of the other soil layers ; the range of co2 concentration varied with air temperature begins to increase in turn from woodslay and shrublay to herbage

    由於植被覆蓋類型不一樣和所處的層位以及本身性質，表層帶巖溶生態系統各層的coz濃度隨溫度變化的幅度不一樣，林地表層coz濃度變化的幅度比深部大，裸地土下e0 。 zcoz濃度變化的幅度比表層和底層大，林層、灌層和草層coz濃度變化的幅度依次變小。
