The semi-arid valley scrubs in the upper reaches(31°15′ 32°32′N,103°10′ 103°54′E)ofthe Minjiang River distribute discontinuosly along the river banks and Occupy a300 400m widebeIt on the slopes.This special vegetation is researched systematically in view of communitybiology,distribution and characteristics of communities. The studied results of the lifeformspectrum show that Ph>H>G>Th>Ch , which reflect that there iS a warm,rainy summer anda long winter.The scruds may be classified into 2 formation groups,7 formations and 10associations,which can be integrated as follows:Form. 1 Campylotropis wilsonii+Indigofera lenticellata+AjaniaForm. 2 Bauhinia Faberi var microphylla+Ceratostigma minus+Indigofera lenticellata+Ajania potaniniiForm. 3 Bauhinia faberi var.microphylla+Sophora viciifolia+Ceratostigma minus+INdigofera lenticellata+Ajania potaniniiPorm. 4 Indigofera lenticellata+Ceratostigma minus+Ajania potaniniiForm. 5 Convolvulus tragacanthoidesForm. 6 Caragana tibeticaForm. 7 Cotoneaster gracilis+Caragana boisi+Amygdalus tangutica+Berberis SP.Among these formations Form. 1,3 are most widely distributed, while Form. 5 manifests asemi-desert landscape.

The grassland communities of NeiMongol are particularly studied,the characteristics of communities about frequency and biomass are considered.With novel scalehierarchy theory,from different scales the relationship between stability and species biodiversity are tested,by use of the line regression.The results are as follows:1)The stability of species constitutions in the communities denoted by the frequency fluctuation are not correlated with richness and the index of Shannon wiener;2)The biomass fluctuations are significantly and negatively correlated with the indices of biodiversity but positively with dominance.The proportion of low fluctuations population is significantly and positively correlated with richness,eveness the index of Shannon wiener and negatively with dominance.There are a positive relaitonship of biodiversity to stability and a negative relationship of dominance to stability;3)The effects of scale to the relationship between diversity and stability are fremendous.The relationships between the biodiversity and structure stability of community are different under different scales.In the small local scale,there is no relation between the indices of stability (the proportion of low fluctuation population and the fluctuation of biomass) and the indices of biodiversity,but in large regional scale they are significantly correlated.

以位于内蒙古高原中东部的锡林郭勒草原的代表性植物群落做为研究对象,在不同的空间尺度上,以生物量涨落、频度涨落及微涨落种群比例做为群落结构稳定性的度量指标,与表示草原植物群落物种多样性的丰富度指数、Shannon-wiener指数、均匀度指数进行了直线回归分析,主要结果如下:1)以频度涨落反映的群落结构稳定性与丰富度指数,Shannon-wiener指数不相关;2)生物量涨落在区域尺度上(荒漠草原-典型草原-草甸草原)与丰富度指数、均匀度指数以及Shan-non-Wiener指数呈正相关,即群落多样性越高,其结构稳定性越高;3)尺度对多样性与稳定性关系起着十分重要的作用.在群落尺度上(群系内三个群落类型之间相比较),微涨落种群比例、生物量涨落与几个多样性指数都不相关,说明物种多样性对于全局稳定性起着更明显的影响.

The vegetation in Southern Peninsula (including Ardley Island) was classified according to the composition of species (especially dominant species),physiognomy and structure, and ecology factor, into tundra,meadow,marsh and aquatic vegetation; among which the formation and association were described. The formation and distribution of these communities were dependent on the water supply and the stability of the substrata. The paper discusses also the distributional pattern of vegetation from coast to hill top,...

The vegetation in Southern Peninsula (including Ardley Island) was classified according to the composition of species (especially dominant species),physiognomy and structure, and ecology factor, into tundra,meadow,marsh and aquatic vegetation; among which the formation and association were described. The formation and distribution of these communities were dependent on the water supply and the stability of the substrata. The paper discusses also the distributional pattern of vegetation from coast to hill top, characteristics of communities, comparative study on the species number, evenness and diversity among each formation and among different habitat, and some suggestions on vegetation conservation was also attempted.

根据群落的种类组成、外貌和结构、生态因素将菲尔德斯半岛南部(包括阿德雷岛)的植被划分为冻原、草甸、沼泽、水生植被四大类型。对下属的群系和群丛进行了描述。这些群落的形成与分布主要依赖于水分状况和基质的稳定与否。论述了从海边到内陆的山顶群落的分布规律、植被特点,并对不同群系、生境进行了群落植物的丰富度(物种数)、均匀度和多样性对比。从对比结果提出对保护工作的建议。
