Based on the established GIS of the Oncomcelania Snails' distribution in Dongting Lake, the author analyzes the environmental condition of the Oncomcelania Snails' habitates comprehensively by the spatial analyzing technology. The results are as following: firstly, the predominant vegetation of Oncomcelania Snails habitat is reed and sedgy. The habitats with reed has a higher livability than with sedgy as dominating vegetation. However, the diffusion of Oncomcelania Snails is much serious in the habitats with sedgy. Secondly ,the predominant soil type of the Oncomcelania Snails breeding area is temporary submergic paddy soils, which is in weak acidity environment, of that PH value is 5.5--7.5, and the organic content is in 2---3%. Thirdly, the 80 percent of the Oncomcelania Snails breeding area, the normalized difference vegetation index of that is in 0.100-0.375%, and the soil humidity of that is in 0.202—0.507, and the distance to the water of that is in 10-230 meters.
在已建立的洞庭湖区江滩钉螺分布地理信息系统的基础上,运用GIS空间分析技术,对钉螺孳生地的环境状况作了比较全面的分析,发现洞庭湖区江滩钉螺孳生地植被类型主要为芦苇和莎草类,钉螺在莎草地带中的存活率高于芦苇地带,而钉螺感染情况最严重的在芦苇地带中;孳生地的土壤类型主要为潴育性水稻土;孳生地土壤PH值处于5.5-7.5之间的弱酸性环境,有机质含量处于2-3%之间;80%孳生地的植被标化指数在0.100-0.375之间、土壤湿度在0.202-0.507之间、近水源距离为10-230之间。

The species diversity of Dipentodon sinicus communities in Yushe National Forest Park of Guizhou province was studied based on the quadrate method. The results showed that Rosaceae, Ericaceae, Betulaceae, Fagaceae, Theaceae, Lauraceae, Caprifoliaceae, Cornaceae were the dominant families in D. sinicus communities of Yushe National Forest Park. In the 10 sample plots, there were 8 which were absolutely dominated with D. sinicus population, the importance value came up to 135.69 on average, and it was far higher than the others. For D. sinicus communities, the abundance index (2.847), Simpson index (0.601), Shannon-Wiener index (1.523), probability of inter-specific encounter (0.601) and species evenness (0.569) of the tree layer were lower than those of the shrub layer (5.580, 0.830, 2.377, 0.829, 0.672, respectively) on the whole. It markedly showed a species diversity characteristic of the mixed broadleaved evergreen and deciduous forest in middle subtropics. In the 10 sample plots, the species diversity level of Q1 was the highest, followed by Q3, Q5 and Q6 was the lowest.
摘要运用样方法对贵州省玉舍国家级森林公园稀有保护植物十齿花群落的物种多样性进行了研究,结果表明:玉舍国家级森林公园十齿花群落以蔷薇科、杜鹃花科、壳斗科、桦木科、山茶科、樟科、忍冬科、山茱萸科等为优势科;10个样地中有8个样地以十齿花种群占绝对优势,其平均重要值高达135.69,远远高于其它种群;十齿花群落乔木层物种丰富度为2.847、Simpson指数为0.601、Shannon-Wiener指数为1.523、种间相遇机率为0.601、均匀度指数为0.569,总体上均小于灌木层(分别为:5.580、0.830、2.377、0.829、0.672),表现为较明显的亚热带常绿落叶阔叶混交林的物种多样性特征。10个样地中,Q1的物种多样性程度最高,Q3次之,Q5和Q6最小,多样性程度最低,10个样地的物种多样性排序为Q1>Q3>Q9>Q7>Q2>Q4>Q10>Q8>Q5>Q6。

Thunbergii trees were established, and the sun survivorship curves were drawn with field data. The results showed that in the three plots, the height and basal diameter growth of regenerated young P. thunbergii trees had exponential, linear, and quadratic functional relations with age and the age structure was of spindle, discrete, and pyramid types, respectively. Most of the regenerated young trees were distrbuted at 0.3-1.2 m from their nearest standing trees, and the individuals of the young trees decreased near to or far from the nearest standing trees. Inplots Ⅰ and Ⅲ, the expected average life of regenerated young P. thunbergii trees had a decreasing trend with their increasing age, and the survival number of the population also decreased with increasing population age. The survivorship craves of regenerated young P. thunbergii trees in the two plots approximated to the type of Deevey Ⅱ, indicating that the young P. thunbergii populations in the plots were at stable development stage. The population structure of regenerated young P. thunbergii trees in plot Ⅱ was lesser integral, suggesting that the population was of declining types being related to human disturbance, slope and other environmental factors.
结果表明:(1) 3个样地中幼龄植株高生长、基径生长与年龄均分别呈指数函数、直线和二次函数关系;(2) 3个样地黑松幼龄植株年龄结构存在着明显差异,分别表现为纺锤形、残缺型和金字塔型;(3)幼龄植株主要集中分布在距最近立木0.3~1.2m,离立木越近或越远幼龄植株均逐渐减少;(4)对样地Ⅰ和样地Ⅲ黑松幼龄植株生命表和存活曲线的分析表明,随年龄的增加,黑松幼龄植株生命期望值基本上呈递减趋势,黑松幼龄植株种群存活数也随着年龄的增加而降低;样地Ⅰ和样地Ⅲ黑松幼龄植株种群存活曲线近似于Deevey Ⅱ型,表明2个样地黑松幼龄植株种群处于稳定发展阶段;(5)样地Ⅱ幼龄植株种群结构很不完整,表明该种群属于衰退型,与人为干扰及坡度等有关。

While the morning-band has not beclouded my eyes While the cord of the Fates is still dimly evident In the dusk, I am busy In twining the life in dust Mosquitoes are not tired of reciting doggerels again and again I am immaculate to respectively listen to them Moths are looking for sunshine in sunshine I am not intent to bluntly point it out Time is like starlight Soundlessly trickling from reticulations I only hold the undivided attention To weave the life in dust Oh, when will the silk thread As long as a dream be ended In my bustling steps Where is the unchangeable purpose A gigantic beetle Has destroyed my dream that is as long as the silk thread What has dropped from the sky to the earth also includes The life I am weaving in dust
趁黑纱尚未蒙蔽我的眼睛昏黄中这一线命运的绳索还依稀分明,我要忙着织完这尘埃中的生活蚊子不厌其繁地朗诵打油诗我无暇聆听飞蛾在光明中寻找光明我无心点破时间如星光从网眼里无声地滴漏我只一心一意纺织这尘埃中的生活梦一样长的丝线啊何时才有个尽头在我忙乱的脚步里哪里有不可更改的目的一只巨大的甲壳虫摧毁了我丝线一样长的梦从空中坠落在地的,还有这我正在尘埃中编织的生活
