浅析划定矿区范围的若干原则

划定矿区范围依据的法律、法规及行政主管部门的规范性文件众多。在划定矿区范围时,现行的《安徽省矿产资源总体规划》（2008～2015年）应当严格执行;安徽省经济和信息化委员会联合相关厅、局发布实施的行业准入条件必须满足;不影响已有矿业权人的权益也是一项基本原则。     

Estimation of Surface Temperature and Rainfall in Ghana

Geografisk Tidsskrift, Danish Journal of Geography 97: 76–85, 1997.

Daily Meteosat images for 1989 have been analysed for the purpose of mapping surface temperature and rainfall in Ghana. The images in the time-series are georeferenced and the maximum value composite (MVC) technique is applied to the temperature calibrated IR-channel images after a cloud screening of the images. The cloud covered areas are outlined and traced using the Meteosat visible channels. Stratiform clouds are detected using surface albedo while cumuliform clouds are detected based on a technique calculating the spatial variability within a 5 pixel by 5 pixel window around each point in the image. The cloud covered parts of the scene are then delimitated by comparing the normal albedo values and the spatial variance in albedo.

The paper then discusses how the outlined procedure can be applied in an environmental monitoring context. For each of the months June to November 1989 the mean monthly rainfall amounts at 35 meteorological stations are plotted against the mean surface temperature. It is found that apart from the month of June statistical significant linear relationships are obtained and that the scattering around the line is decreasing for increasing sampling length.     

Influence of uncertainty in delimitation of seismic statistical zone on results of PSHA

The seismic hazard of research area is evaluated by probabilistic analysis method for three different seismic statistical zone scenarios.The influence of uncertainty in seismic statistical zone delimiting on the evaluation result is discussed too.It can be seen that for those local sites along zone‘s border or within areas with vast change of upper bound magnitude among different scenarios the influence on seismic hazard result should not be neglected.     

遥感技术在海域勘界中的应用

本文从遥感信息机理出发,探讨遥感技术在海域勘界中的应用:综合运用遥感图像的分类技术获取涉界区的资源空间分布和利用现状,利用影像的空间结构和纹理特征获取地形地貌特征信息,利用地理位置精校正的影像进行海岸线修测,通过不同时期的遥感影像获取岸滩动态变化,进行岸滩稳定性评估.在福建泉州海域应用结果表明:采用遥感技术可快速、客观、准确地获取支撑海域勘界所需的空间信息,但定位精度主要依赖于遥感数据的空间分辨率,而且由于遥感数据以像元阵列表示空间分布,较小的码头、潮沟、岛礁等地物可能与其他地物构成混合像元而未能被识别出来.     

地震统计区划分不确定性对场点地震危险性计算的影响

用3个不同的地震统计区划分方案，采用概率地震危险性分析方法，分别计算了研究区地震危险性，并讨论了地震统计区划分方案的不确定性对地震危险性结果的影响．结果表明，地震统计区划分方案的不确定性，对局部场点的地震危险性分析结果的影响是不容忽视的．这些场点通常位于地震统计区边界，以及不同方案震级上限变化大的区域．      

基于地质遗迹集中度的地质公园边界划分

中国地质公园在快速发展中出现了边界划分随意、公园面积过大等问题,表明地质公园建设理论较薄弱.该文提出地质遗迹集中度的概念,可表征地质遗迹的分布特征,并具有计算简便、易于操作的特点;将其应用于封开国家地质公园规划修编,可有效控制地质公园面积过大的倾向,并使地质公园空间结构紧凑、主题突出.
