ANALYSIS ON THE SPATIAL DISTRIBUTION VARIATION CHARACTERISTIC OF URBAN HEAT ENVIRONMENTAL QUALITY AND ITS MECHANISM——A Case Study of Hangzhou City

Urban heat environmental quality(UHEQ) is affected by the interacting of weather condition and underlying surface framework of urban area .In the last two decades,many researchers from domestic and overseas have studied many problems at the aspect of urban heat environment such as urban heat islands ,urban air temperature and their rela-tion with urban land cover,city population,air pollution etc,In the recent years,Hangzhou,acting as a center city of Zhejiang Province in China,its urbanization quantum and quantity have both changed greatly,in particular ,representing as business affairs building,resident real property and all kins of specialty market having arisen in built-up zone,Based on Landsat TM images data in 1991 and 1999,urban underlying surface temperature value and Normalized Difference Vegetation Index (NDVI) were calculated using image interpreting and supervised classification technique by remote sensing software ERDAS image 8.4,The relation model between urban underlying surface temperature (UUST )and urban air temperature was setup according to the certain correlation patten .Reference to the relational standard of assessing human comfort and other meteorology data of Hangzhou City in summer,the spatial distribution characteristic and the spatial varia-tion degree of human comfort of heat environmental quality are estimated and mapped on a middle scale,that is ,in six districts of Hangzhou City .Then the paper reveals the main characteristic of spatial variation from 1991 to 1999.Lastly,the change mechanism is analyzed and discussed from the viewpoint of city planning,construction and environmental protec-tion.     

陕西白河县月儿潭绿松石与次生磷钙铝矾研究

对陕西省白河县月儿潭风化严重的绿松石样品进行了岩石薄片观察、化学成分测试、X射线粉晶衍射和红外吸收光谱分析等研究.结果表明,绿松石风化分解由天蓝色退色成黄绿色,最后变成白色,结构也由致密细腻变得松散多孔,主要原因是发生了硫酸根对磷酸根的交代作用,最终的交代产物主要是磷钙铝矾.     

AN ECOLOGICAL STUDY OF BENTHIC ORGANISMS IN THE NEARSHORE WATERS TO THE WEST OF TAIWAN STRAIT

In seven cruises on benthic organisms in the nearshore waters(>50 m) to the west of the Taiwan Strait(23°20''-25°54''N,117°11''-119°58''E) in 1961-1964,altogether 189 stations of quantitative grabbing and 33 stations of qualitative trawling were made.
Altogether 392 species of benthic organisms have been identified.The composition was dominated by nearshore shallow water species,with tropical and subtropical species absolutely dominant.The total average of biomass was 38.0 g/m² and average density,116.0 ind./m².The communities of benthic organisms in the area can be classified into five communities namely,(1) Amphiura sp.-Acaudina molpadioides Community;(2) Protankyra asymmetrica-Arnphioplus pracstans-Murex trapa Community;(3) Modiolus meicalfei-Phyllophorus liuwutiensis-Armandia letocirris-Nephtys sinensis Community;(4) Branchiostoma belcheri-Solenr oseomaculatus-Marphysa sinensis- Onuphis eremita Community;(5) Iconomtra japonica-Barbatia decussata Community.

应用多年的实测资料 ,分析了曹娥江河口高水位成因 ,结果表明 ,曹娥江河口洪水位具有山溪性和可冲性的特点 ,人类活动对高水位有较大影响。应用统计分析法和成因分析法推求 1 %设计高水位 ,讨论了成因分析法中上、下边界条件的选取 ,其选取原则对其他潮汐河口确定设计高水位具有借鉴意义     

一种具有巨大经济价值的海洋矿产资源--砂石土

砂石土指第四纪堆积的泥、土、砂，为一种极为重要的资源。我国具有丰富的海洋砂石土资源。以广东海域为例，通过资料的综合分析，探讨了海岸砂石土资源的重要作用，并提出其开采应注意的问题。     

台湾的弧陆碰撞研究及其地层沉积构造研究年表

对台湾及其邻近地区典型板块构造弧陆碰撞运动的研究历史沿革与代表性观点进行了较为全面的介绍;将1977年颜沧波有关台湾及其邻近地区典型板块构造弧陆碰撞运动研究的观点与30年后黄奇瑜教授的研究成果进行了对比性介绍;同时介绍了反映台湾及其邻近地区典型板块构造弧陆碰撞运动的地层沉积构造综合研究年表。     

真鲷三倍体诱导初步研究

在真鲷Pagrosomusmajor三倍体诱导研究中，对染色体倍数的分析表明，受精卵受精5min后，在1．5℃冰水中处理5min，可获得17％的三倍体诱导率和28％的嵌合体比率，染色体数分别是：2N＝48，3N＝7Z，嵌合体50—68。仔鱼红血细胞测量和组织切片分析显示，三倍体和二倍体的红血细胞核直径（长径，下同）、视网膜神经节细胞核直径和中脑细胞核直径大小存在差异，其比率分别是1．42，1．35和1．41，这种差别必然导致三倍体鱼和二倍体鱼在代谢与功能方面的差异。应加强对鱼类三倍体形成机制及应用潜力的研究，同时注意开展其生理学、生化学和行为学的比较研究。     

台湾海峡西岸林进屿古火山喷口群的地貌成因

由纯火山岩组成的林进屿位于台湾海峡西部近岸海中，熔岩喷发年代为上新世。这个典型的火山岛自早全新世海进到达这里以后的6－7ka以来，长期处于大风浪冲击的环境而导致海岸纸后退，并在海蚀崖滩上塑造出各种奇形怪状的火山地貌，裸露出一系列小型的古火山喷口群和火山颈。研究林进屿火山岛的地貌成因不仅具有一定的科学意义，尤其将引起国内外地学界特别是海峡两岸学术界的兴趣。     

我国近海沉积层地震速度特征

我国近海纵向上发育了新生界、中生界碎屑岩和古生界沉积地层。在分析整理收集到的地层速度资料的基础上,分析了地层速度的变化规律:沉积层地震速度随地层的埋深增加而增加,新地层速度低、老地层速度高;欠压实地层的砂岩速度与泥岩速度基本相当或低于泥岩速度,正常地层的砂岩速度大于泥岩速度;砂岩储层的速度随孔隙度的增加而降低,流体成分的变化对速度的影响不大。
