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

EMERGY ANALYSIS OF GRAIN PRODUCTION SYSTEM IN JIANGSU AND SHAANXI PROVINCES     

LIUXin-wei CHENBai-ming ZHANGDing-xiang 《中国地理科学(英文版)》2004,14(3):209-214

Efficiency and sustainability of grain production are now important in China. In this study, the grain production systems of Jiangsu and Shaanxi Provinces were compared, to analyze their efficiency and sustainability in terms of utilization of natural resources, inputs of purchased energy and materials, and outputs. Flows of energy and materials between environment and human society were identified, and the natural and human work involved in generating inputs as materials or energy were valued in terms of equivalent amount of solar energy required for their production using emergy method. The results showed environmental resources were continually playing a less important role in the systems, when inorganic subsidiary emergy inputs increased drastically while organic ones decreased or increased little. Deterioration of input emergy structure affected the systems‘ efficiency and sustainability, resulting in emergy investment ratios and environmental loading ratios increasing while yield ratios and sustainability indices decreasing. In general, efficiency and sustainability of grain production in Jiangsu are worse than those in Shaanxi. This analysis also suggested that inorganic subsidiary emergy should be introduced properly, and peasants in Jiangsu should utilize natural conditions wisely while those in Shaanxi pay enough attention to soil and surface water conservation.  相似文献   

切实保障失地农民的长久收益     

《江苏国土资源》2003,(7):1-1

中央反复强调，没有农民的小康，就没有全国人民的小康：没有农村的现代化，就没有国家的现代化。农民富才能全民富，农业兴才能百业兴，农村安才能天下安。“三农”问题说到底就是土地问题，土地是农民的“命根子”，是农民最可靠的社会保障。国土资源部门作为涉农部门，做好“三农”服务工作，特别是做好失地农民的征地补偿安置和基本生活保障工作，肩负着重要的历史使命。  相似文献

周末风暴（十）——亲历南极大救险     

王自馨 《海洋世界》2005,(10):41-44

饮恨雷岛经历了昨晚长城海湾的风雪之夜,奥立格虽疲惫之极,却因出艇搜救未果而久不能眠。清晨7点51分,他突然接到韩国站呼叫,通报长城站在沙坝一带海岸发现遇险小艇物品,并请求加强对阿德雷岛一线继续搜寻。于是他分析了韩国人员在昨夜恶劣暴风雪中翻艇落水可能的过程,很快设想了自己下一步营救计划。8点30分,一辆改装的苏式装甲运兵车,装载着一支由俄罗斯队员为主的7人搜救队,急速向阿德雷  相似文献
