聚力“整体智治” 提升六大能力——德清县打造地质灾害防治新格局     

徐斌  吴法昌 《浙江国土资源》2021,(4):26-27

德清县紧紧围绕“不死人、少伤人、少损失”的总目标,聚力“整体智治”,充分运用云计算、大数据、物联网、人工智能等现代科学技术,扎实推进地质灾害防御体系和智控能力建设,整体提升地质灾害综合防治水平,努力实现从单部门应对单一灾种向多部门联动应对灾害链转变,从人防为主向人防技防并重转变,从隐患点管理向风险防控转变,有效破解地质灾害治理难题,最大限度减少地质灾害给人民生命和财产造成损失,已连续14年实现了地质灾害“零伤亡”,为“平安德清”建设提供地质环境安全保障。  相似文献

秦岭山地气候变化的地形效应     

孟清  白红英  赵婷  郭少壮  齐贵增 《山地学报》2020,38(2)

研究不同地形下的山地气候变化对于植被生长、不同动物种群的生存习性及对气候的应激性有重要意义。本文基于陕西秦岭地区1959—2016年32个国家站的日气温和降水资料,采用Anusplin插值法、标准化降水蒸散指数(SPEI)、稳健回归和Theil-sen回归法等方法分析了山区地形对气候变化的影响。结论如下:(1)58年来秦岭四个坡向上年均温度随着海拔的升高呈现显著下降趋势,年降水随着海拔的升高呈现不同程度的上升趋势。温度随坡度的增加表现出下降趋势;除秦岭南坡西段外,降水随着坡度的增加呈现出上升趋势,但均不显著。(2)年尺度上,秦岭山地南坡和南坡东段的气温呈显著增温趋势,南坡西段和北坡呈不显著增温趋势;四个方向上的降水均呈显著下降趋势。秦岭山地四个方向上的干湿等级为正常,北坡和南坡西段的干湿状况一致,58年年均SPEI均为0.07,南坡东段较暖湿(0.08),南坡较暖干(0.05)。(3)季节尺度上,秦岭山地四个方向上除了夏季外,其他季节的气温均表现出不同程度的升温趋势,降水均呈下降趋势。秦岭四个方向上四季干湿变化属于正常等级。秦岭北坡出现春季干暖化趋势;南坡秋季较暖湿;南坡东段和西段的冬季呈暖湿化特征;南坡西段夏季呈现暖干化特征。  相似文献   

PRELIMINARY STUDY ON THE FLOODING AND DROUGHT CLAMITY DURING PAST 1500 YEARS IN THE HAI′AN REGION，JIANGSU PROVINCE   总被引：1，自引：0，他引：1  

ZHANGQiang  CHENGJi 《中国地理科学(英文版)》2002,12(2):146-151

Collection and arrangement of the historical records of climatic changes and environment evolution,espectial-lyin the aspect of calamities,are made on the history documents of past 1500 years about Haiˊan region,Jiangsu Province.There existed two obvious flooding-drought frequently-occurring periods:one was from 1550 AD to 1850 AD and another was 100 AD to 1200AD.The period of 1550 AD to1850 AD is interrupted by two relatively arid and cold climatic periods:one was from 1630 AD to 1700 AD and another was 1750 AD to 1820 AD.The main characteristic of the calamity periods is that they occurred by turns,and sometimes,both drought and flooding occurred in the same year.The instability of the climatic changes in the Little Ice Age may be the main reason of the frequently-occurring flooding and drought in Haiˊan region.Research results also show that the frequently-occurring periods of flooding and drought is in close relationship with the solar activity,and therefore,occurrence of the flooding and drought may be in relation with the intensity of the solar activity.This hypothesis may need further study in the future.  相似文献

一种新的振幅滤波法在化磁极中的应用     

丁凤仪  刘建军 《地球科学与环境学报》1995,(4)

本文针对低纬度地区频率域化磁极存在的问题，在频谱分析的基础上，提出了一种新的滤波方法即振幅滤波法。该方法能将低纬度地区化极磁场的频谱恢复到垂直磁化磁场的频谱，大大提高了低纬度地区化磁极的精度。  相似文献

Discovery of 13 New Variable Stars in the Field of the Open Cluster NGC 2168 （M35）     

Juei-Hwa Hu  Wing-Huen Ip 《中国天文和天体物理学报》2005,5(4):356-362

A wide-field time-series CCD photometric survey of variable stars in the field of the open cluster NGC 2168 was carried out using the BATC Schmidt telescope. In total 13 new variable stars are discovered with three W UMa systems, one EA type and two EB type eclipsing binaries (one of them could be a W UMa system), and seven pulsating stars including three candidates of δScuti stars.  相似文献
