Beijing is provided with typical urban landscape, forest land is the maximal and basal landscape patch type (area proportion 42.534%), glebe field (28.754%),spinney land and urban (26.912%) and town residential landuse (10.344%) are main landscape patch categories in Beijing. From landscape, landscape patch types and landscape patch categories levels, landscape patch distributing centralize, and patch shape is simple, main landscape patch fractal dimension indexes are under 1.1, so urban landscape pattern is high influenced by human disturbance.2. From 1985 to 2007, Beijing landscape pattern variational characteristics are as follows:(1) During 1985-2007, patch types and categories change is little, but area and patch number of patch types and categories change distinctly. Town residential landuse area increased 7.66% of Beijing total area, farmland and forest land area decrease in the mass. The total patch number increased at first then decreased. taking one with another, the total number is decreasing, and patch number of farmland and forest land are most distinct.
本研究的主要研究结果如下:1、北京市具有典型的城市景观特征,林地用地的面积占市域面积的42.534%,为基质景观斑块类型,旱田(28.754%)、灌木林(26.912%)、城镇用地(10.344%)是北京市主要景观斑块种类;从景观、景观斑块类型以及景观斑块三个层次的研究均表现出北京市各景观斑块类型及景观斑块集中分布的现象十分突出,斑块形状简单,主要景观斑块种类的景观分维度指数值均不足1.1,表明城市景观格局受到了较大的人为影响。2、北京市1985-2007年间城市景观格局的主要变化特征表现为以下几个方面:(1)在研究时段内,北京市景观斑块种类变化不大,景观组分面积和斑块数变化明显,其中最为显著的是北京市城镇建设用地面积呈单纯的增加趋势,增加幅度为北京市总面积的7.66%,农业用地与林地的面积虽呈波动变化但总体呈减少趋势;景观斑块数量先增后降,总体呈下降趋势,其中耕地与林地斑块数的变化最为明显。

We will investigate the actuality of stony deserts in Guizhou, and divide their types on the basis of their intensity, covering rate of soil and vegetation and amount of species, and stduy the influence factors of forming different stony desert types in more coercing, and explore the ratio of influence factors in the different stony desert areas and the evolutionary mechanism of different stony desert types. Finally,we will stduy the growing conditions and species of arboreous in different geology, land form,hydrology region for natural lithogenic forest and artificial forest, and the natural conditions for failing in many artificial forest,and the reconstruction mechanism in different stony desert type regions.

The soil erodibilities are compared and appraised for the majority of the soil types in Ningxia. The method published by D. W. Fryrear et al is adopted to calculate erodible fractions for the soils in Ningxia. The erodibilities of main soil types are compared and analyzed. Spatial distribution of soil erodibilities in the region can be perceived on the Map of Ningxia Soil Erodibility. The map is based on the digitized map of soil types of the all region by means of the geographical information system of Region Manager. Evaluation results show that erodible soils occupy a large portion of the total area of the region.(3) The third task is evaluation of effects of human activities for farming on soil erodibility. Tillage and cultivation can alter soil properties. The paper, based on the discussion on the characteristics of farmland suffering wind erosion in the region, analyzes the contents and intensities of farming disturbing surface soil. Emphasis is paid on the effect of farming on erodibilities of each type of soil.
W Fryrear等人的计算土壤可蚀部分含量的方程,此方程的自变量包括土壤有机质、碳酸钙、沙粒含量、沙粘比,计算了宁夏主要土壤类型表层的可蚀含量,进而比较它们的可蚀性,并以宁夏土壤分布图为底图用地理信息系统建立了宁夏土壤风蚀数据库,完成了宁夏土壤可蚀性图,评价结果显示宁夏地区主要的土壤类型较容易遭受风蚀;(3)农业经营对土壤风蚀的影响及其评价,在分析宁夏农业土壤遭受风蚀特征的基础上,首先讨论了农业活动对土壤理化性质的干扰,评价主要耕作栽培措施对土壤风蚀的影响,选取粗糙度、表面结皮、可蚀颗粒含量、留茬和有效时间为指标,用打分方法作了评价。

In order to explore the grain-size distribution characteristics and geo-genetic types of land desertification in Mo Us desert, the research on the grain-size characteristics of sediments since late Pleistocene has been carried out in the desert area and neighboring area such as inside desert, sand covered loess plateau, loess plateau and river valley. The research result shows that sediments of different geologic genetic types are the fundamental material source of sandy desertification in these areas and the distinguishing of different types of the sediments is the theoretical basis of classification of different geogenetic type of sandy desertification. The contribution of different geological roles on the land desertification and its significance to prevent and deal with the land desertification have also discussed.
为了研究毛乌素沙地沉积物的粒度特征与土地沙漠化的地质成因类型,通过系统研究沙地及相邻地区晚更新世以来在沙地内部、覆沙黄土区、黄土高原和河流谷地与湖泊等不同地质构造地貌条件下所形成的沉积物粒度特征,指出不同地质成因类型的沉积物是这些地区土地沙漠化的物质基础,区分不同类型的沉积物也是构成不同地质成因类型土地沙漠化分类的理论基础,探讨了不同地质作用对土地沙漠化的贡献及其对土地沙漠化防治方面的意义。

The HPV positivity amongst the group of women with no cervical abnormality was 43%, while that in women with cervical dysplasia and cervical cancer was 81.2% PCR products from 89 HPV positive cases were genotyped by LiPA, of which 49 cases were single HPV infected concerning 11 different HPV types and the commonest type was HPV-16, occurring in 25(51%) of all single HPV infected cases. The other 40 specimens contained multiple HPV types comprising 16 different HPV types. Although double infections(n=25) prevailed, triple(n=9),quadruple(n=3) and quintuple(n=3) infections were also found. PCR products of four HPV positive cases failed to be classified by LiPA. Sequencing analysis revealed that these 4 cases were HPV-66 which was not included in LiPA probes. Follow-up data of 12 cases confirmed the HPV genotyping results. Conclusion The LiPA for HPV genotyping is easy to perform.
结果 155例妇女子宫颈刮片中HPV DNA检出率为60%,其中在宫颈细胞学检查正常或仅有炎症病变的妇女中HPV DNA阳性率为43%,而在宫颈细胞增生不良或宫颈细胞癌的妇女其阳性率为81.2%。93例HPV阳性的标本中,89例利用LiPA成功地作出了基因分型,其中单独一型HPV感染为49例,涉及11种不同基因型HPV,最常见的型别为HPV 16,占单独感染的51%(25/49);另40例为不同型别HPV重叠感染,涉及所有16种HPV基因型别,二重感染占主导地位(n=25),同时也检测出其它多重感染。4例HPV阳性的标本应用LiPA未能作出基因分型,DNA序列分析显示这4例为HPV 66感染,此型别不包括在LiPA所标记的探针内。12例随诊资料显示了LiPA的物异性及高度的重复性。

Here we clarify that areal-type of a genus is defined by concluding distributions of all species in the genus, therefore specific distribution types are not the same as their generic areal-types except monotypic genera. Similarities of composition of areal-types between compared regional floras do not necessarily represent their floristic similarities because the same generic areal-type can be composed by different genera from different plant families.
根据植物区系学理论,属的分布区是该属内所有物种的分布区的集合,除单种属外,不能直接套用属分布区类型作为该属内各个种的分布区类型;亲缘关系疏远的不同植物属可以有同样的分布区类型,若把不同地区植物区系各地理成分的比例关系的类似性解读成各地区间植物区系的亲缘关系,显然是不适合的。
