构建“三强三化”保障体系 推进数字化档案建设取得实效     

莫国庆  徐士澄  王杨军  沈妍琳 《浙江国土资源》2021,(4):45-46

在城市规模不断扩张的当下,自然资源档案的数据量飞速增长,内容日趋多元,传统模式下的档案管理手段方法已较难满足时代发展需求。为此,杭州市规划和自然资源局江干分局紧紧围绕职能机构改革这一重要契机,全面推进档案信息化建设迭代升级,以数字化转型为引领,不断构建制度规范化、采编智能化、运用便利化的服务体系。近年来,该局通过不懈努力,在业务档案方面实现了100%数字化覆盖,连续十一年档案年检考核优秀,2021年被浙江省档案局评选为“示范数字档案室”。  相似文献

东阳市自然资源“一体化”综合业务办公模式探索     

楼慧峰  陈军平 《浙江国土资源》2021,(1)

2018年3月,自然资源部成立。2019年东阳市自然资源和规划局内部“三定方案”落地,实现东阳市自然资源管理机构由“分”到“统”的转变。这次机构改革不是对机构的简单合并或调整,而是更高层级下的职能重构和业务重组,需要更深层次的思想理念转变。自然资源管理部门,需要突破之前部门各自为政的困局,建立“一个整体”的概念,把工作放到自然资源的大局中通盘考虑,培养系统化的思维模式。同时需要进一步精简下放有关行政审批事项、强化监管力度,为保护和合理开发利用自然资源提供科学指引,更好发挥政府作用,强化自然资源管理规则、标准、制度的约束性作用。  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

FEASIBLE STUDY ON THE INTEGRATION SYSTEM FOR THE SPACE MONITORING OF MAJOR EARTHQUAKES AND VOLCANOES IN TERRESTRIAL LAND   总被引：1，自引：1，他引：0  

BOLi-qun 《中国地理科学(英文版)》2002,12(4):350-353

With the rapid development of space technology, earth observation technology and sky observatory technolo-gy, they have played a more and more important part in monitoring and predicting of earthquakes and volcanoes in the terres-trial land. In recent years, the related agencies have done the experiments and researches on monitoring and predicting ofearthquakes and volcanoes in the forewarning period by means of many approaches, such as satellite thermal infrared re-mote sensing (TIRS), Global Positioning System (GPS), differential interferometric synthesis aperture radar (D-INSAR),astronomical time-latitude residual anomaly, and Geographic Information Systems (GIS), etc. A quite large number of re-search foundation has been built in the fundamental theories and application methods. The experiments and researcheshave shown that these technology is efficient methods for high frequency crust movement. If the existed separate scientificforces and results are possibly assembled together to form a more complete integration monitoring system with the combina-tion of space, sky observation, ground, deep geology and macro anomaly, it will come into a new stage of monitoring andpredicting of earthquakes and volcanic eruptions.  相似文献   

Ab　Initio　Prediction　of　^29Si-NMR　Chemical　Shifts     

CHUShidong LIYingxia SONGNi GUANHuashi 《青岛海洋大学学报(英文版)》2002,1(1):63-65

The ability of several ab initio models to predict experimental 29Si-NMR chemical shift is examined. The shielding values of trimethylsilyl chloride (A), t-butyldimethylsilyl chloride (B) and allyltrimethylsilane (C) are calculated by GIAO, CSGT and IGAIM methods, using HF/6-31G^*, B3LYP/6-31G^* , HF/6-311 G^**, B3LYP/6-311 G^** and MPWlPW91/6-311 G^** models respectively. The 29Si chemical shifts calculated by GIAO method using HF/6-311 G^** model are highly in agreement with those obtained experimentally. All of the models above reproduce the trends of chemical shifts in all cases studied, suggesting that the models are of practical value.  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
