消除CCD天光背景的一种组合式分割方法

基于迭代阈值法和统计模型提出了一种新的组合式分割方法，该方法精确地描述了天光背景的分布情况，既能够精确确定图像分割的最优阈值，有效地消除天光背景的影响，又可以精确地估计出天光的平均强度，有利于天体亮度的精确计算及暗星的探测。     

Integration of multi-sensor data for landscape modeling using a region-based approach

The increased availability of multi-sensor data, and elevation information in particular, leads to the need of advanced processing methods. In the context of landscape modeling tasks, we concentrate on one central component, the extraction of terrain surface from a Digital Surface Model (DSM). In contrast to conventional mathematical grey value morphology approaches (filtering methods) or to stochastical procedures, we propose an alternative methodology for this task by applying a region-based and multi-scale approach. It consists of segmentation and follow-up fuzzy logic classification based on several features derived from elevation and multi-spectral image data. The satisfying results obtained with a multi-sensor as well as with other datasets show the applicability of the approach.     

山西太原晋祠断裂活动性的初步研究

通过地质调查和地震活动性的研究，把晋祠断裂划分为2段：南西段长20km，为单断型，即由单条断裂组成，断裂在第四纪晚更新世至全新世期间活动强烈，以正倾滑运动为主兼有水平右旋扭动；北东段长5km为平行双断型，即由2条走向完全相同的阶梯状正断裂组合而成。位于盆地边缘的断裂，活动时代为中更新世，位于盆地内黄土台地前缘的断裂，活动时代为晚更新世，断裂的活动有向盆地内部迁移的趋势。     

云南西庄河流域主要栽培作物的农业气候资源分析

云南西庄河流域具有发展粮食和经济作物生产的良好条件。主要粮食作物是小麦、玉米、水稻、杂粮(苦荞、黍)，主要经济作物是茶及桑树。由于作物生长具有复杂的生物物理机制和生物化学变化过程，不同作物对气候条件如光、热、水的需求是有差异的。为了监测西庄河流域气候特征，特地在流域中部设立了一个观测站，获得了该流域的主要气象要素特征值，使主要栽培作物的农业气候资源分析成为可能。本文对西庄河流域的农业气候特点及其对主要栽培作物的影响进行了分析，并进一步提出：西庄河流域属于水稻、桑、烟叶分布区；玉米、苦荞、黍分布适宜区；小麦、茶生态分布最适宜区。     

GPS、GIS技术在西庄河流域滑坡灾害研究中的应用

本文采用了GPS辅助下的野外调查、野外实地填固进行数据采集和室内GIS(ArcInfo7．0)辅助下的数据储存、分析方法，以西庄河山地流域过去发生的滑坡事件为研究对象，初步分析了该山地流域内滑坡事件的时空分布特征及近期滑坡发生的可能趋势。最后，指出GPS和GIS技术在流域滑坡灾害研究中具有广泛的应用前景和优越性。     

Uppermost Tortonian to Quaternary depocentre migration related with segmentation of the strike-slip Palomares Fault Zone,Vera Basin (SE Spain)

The Palomares Fault Zone (PFZ) is one of the main strike-slip brittle shear zones found in the Betics. It is segmented in several faults that have been active between the Upper Tortonian and present day. Data from drill cores in the Palomares area have permitted us to define the geometry and location of sedimentary depocentres related with the PFZ. These data show an eastward displacement between the Upper Tortonian to Messinian and the Pliocene–Quaternary sedimentary depocentres, towards the presently active Arteal fault, which bounds the western mountain front of Sierra Almagrera, showing that deformation along this fault zone has migrated towards the east, from the Palomares segment, with its main activity during the Upper Tortonian and Messinian, towards the Arteal fault, active during the Pliocene and Quaternary.

Characteristics of Non—Point Source Pollution in the Watershed of Miyun Reservoir,Beijing,China

Nitrogen and phosphorus are the major nutrients to cause eutrophication to degrade water quality of the Miyun Reservoir,a very important drinking water source of Bijing,China,and they are mainly from non-point sources.The watershed in Miyun County was selected as the study region with a totoal area of 1400km^2.Four typical monitoring catchments and two experimental units were used to monitor the precipitation,runoff,sediment yield and pollutant loading related to various land uses in the meantime.The results show that the total nutrient loss amounts of TN and TP are 898.07t/a,and 40.70t/a,respectively,in which nutrients N and P carried by runoff are 91.3% and 77.3%,respectively.There is relatively heavier soil eroson in the northern mountain area whereas the main nutrient loss occurs near the northeast edge of the reservoir.Different land uses would influence the loss amounts of non-point source pollutants.The amount of nutrient loss from the agricultural land per unit is highest,that from forestry comes next that from grassland is lowest.However,due to the variability of land use areas,agricultural land contributes a lot to TP and forestry lands to TN.
