中部地区主要城市工业用地的地价杠杆作用     

何文伟 《湖南地质》2009,(2):69-71

1经济发展和工业用地价格状况 我国经济政策上的中部地区就主要包括山西、河南、湖北、湖南、江西、安徽等6省。中部6省土地面积为102．7万km^2，人口3．63亿，分别占全国的10．7％和28．1％。近年来，在国家政策的大力支持和自身努力下，中部地区城市经济都取得了长足的发展，经济发展同时也带动了土地价格的上涨，但工业用地的价格并没有相应上涨。  相似文献

法库地区大型韧性剪切带特征及成因机制     

杨晓波  高恩忆 《国土资源》1996,(2)

通过对辽北法库地区构造岩的观察和研究，确定了本区存在一大型推覆韧性剪切带。根据同构造侵入岩的同位素年龄，确定该韧性剪切带形成时期为海西－印支期，这与天山－兴安褶皱系最终形成时间相一致  相似文献

Utilisation and Management Changes in South Kyrgyzstan＇s Mountain Forests     

Matthias Schmidt 《山地科学学报》2005,2(2):91-104

Using political ecology as its conceptual framework, this paper focuses on the changes in forest utilisation and management of South Kyrgyzstan＇s walnut-fruit forests over the last century The aim of this study on human-environment interactions is to investigate the relationship between actors on the one side, their interests and demands, and the forests and forested lands on the other. Forest resource utilisation and management - and even the recognition of different forest products as resources - are connected with political and socioeconomic conditions that change with time. The walnut-fruit forests of South Kyrgyzstan are unique, characterised by high biodiversity and a multiplicity of usable products; and they have been utilised for a long time. Centralised and formal management of the forests started with the Russian occupation and was strengthened under Soviet rule, when the region became a part of the USSR. During this era, a state forest administration that was structured from Moscow all the way down to the local level drew up detailed plans and developed procedures for utilising the different forest products. Since the collapse of the Soviet Union, the socio-political and economic frame conditions have changed significantly, which has brought not only the sweeping changes in the managing institutions, but also the access rights and interests in the forest resources. At present, the region is suffering from a high unemployment rate, which has resulted in the forests＇ gaining considerable importance in the livelihood strategies of the local population. Political and economic liberalization, increased communication and transregional exchange relations have opened the door for international companies and agents interested in the valuable forest products. Today, walnut wood and burls, walnuts, wild apples and mushrooms are all exported to various countries in the world. Scientists and members of various international organisations stress the ecological value of the forests and are trying to establish nature conservation areas. Nevertheless, it is to fear that a multiplicity of interrelated factors - the present transformation and globalization processes, the appearance of new actors, the local population＇s insecure economic situation and the erosion of managing institutions - are all leading to an intensified and unregulated exploitation of the forests, resulting in their degradation.  相似文献   

亚洲中部干旱区在20世纪两次暖期的表现   总被引：1，自引：0，他引：1  

王劲松  陈发虎  靳立亚  魏锋 《冰川冻土》2008,30(2):224-233

利用亚洲中部干旱区1901-2002年近100 a气温及北半球海平面气压、冬季西伯利亚高压强度指数、西风指数资料,分析了20世纪全球变暖的两个较明显时期在该干旱区的响应特征,以及大气环流变化和太阳活动对干旱区气温异常的影响.结果表明:亚洲中部干旱区对20世纪全球发生的两次暖期的响应特征是有显著差异的.对1920-1940年代全球发生的第一次暖期,亚洲中部干旱区整体并没有响应,仅在其东部的季风影响边缘区有响应;而对1970年代以后发生的第二次暖期,亚洲中部干旱区整体都作出了响应.冰岛低压的异常加深、同时北大西洋亚速尔高压的显著增强,西伯利亚高压强度指数的异常减弱,以及西风指数的异常增强是导致亚洲中部干旱区气温偏高的可能原因,可以初步解释研究区整体对20世纪全球两次暖期响应不同的原因.太阳活动作为外部影响因子之一,对干旱区气温的影响是阶段性的,且在百年时间尺度上,二者并没有显著的相关性.  相似文献
