湘中锰矿控岩控矿构造遥感地质分析

应用遥感信息结合其他地学资料综合分析湘中锰矿构造型式及控岩控矿地质特征，提出东西向和北东向同期构造与台地边缘相带共同控制锰矿的新认识。     

黑龙江省矿业产业结构对经济增长效益分析

区位商是用来分析区域产业结构中专业化部门及其专业化程度的指标。区域某一产业的区位商如果大于1，表明研究区域在某产业部门的集中程度大于较高层次区域平均水平，该产业部门的产品可以“外输”，区位商值越大，则研究区域在该产业部门的集中程度越高；如果区位商小于1，则该产业部门不是研究区域的专业化部门，且产业部门的产品需要“内进”；如果区位商等于1，则表明该产业部门产品供需平衡。     

The Effect of Solar Activity on the Annual Precipitation in the Beijing Area

Using continuous wavelet transform, we examine the relationship between solar activity and the annual precipitation in the Beijing area. The results indicate that the annual precipitation is closely related to the variation of sunspot numbers, and that solar activity probably plays an important role in influencing the precipitation on land.     

成都市冬季重污染日气象条件成因分析及预报

本文通过对成都10个重污染日进行天气学分析,将污染浓度与气象要素进行聚类、研究了重污染日形成原因及污染浓度与气象要素的关系。在此基础上,建立了SO_2、TSP日平均浓度分级预报方程。     

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.     

旧村改造中的若干土地问题分析

近两年来,根据省委、省政府的部署,我市开始实施了"千村整治、百村示范"工程,各地积极地开展了旧村改造.旧村改造是改善城乡环境质量,提高人民生活质量,加快新农村建设,推进城市化进程,实现城乡一体化战略的基本途径之一.旧村改造虽说是一件惠及千家万户的好事,但由于该项工作事关村民很具体的种种利益分配和要求,在旧村改造时应当充分考虑村民的生活、生产、就业等各方面利益.
