基于土地利用变化的生态风险评价——以广西岑溪市为例     

程丽华  曾春阳  郭文娟 《山东地质》2011,(7):53-56

该文以1999年及2009年岑溪市土地利用数据为来源,在GIS的支持下,分析了10年来研究区内的土地利用变化的时空特点及其转化过程,结合土地利用综合指数、耕地垦殖指数、植被覆盖指数、景观破碎度指数评价了土地利用变化的生态风险。研究表明：研究区域内10年间土地利用类型发生了复杂的相互转换,其中林草地、建设用地和耕地为研究区内变化面积最大的3种土地利用类型;受经济快速发展和城市化进程加快的影响,土地利用的广度和深度不断增大,全市土地利用趋于破碎化,土地生态风险程度有所增加。  相似文献   

开发区不同行业工业用地集约利用水平评价——以辽宁省北票开发区为例     

张程光  曲哲  任家强  李楠 《山东地质》2011,(7):57-60

以北票开发区为研究对象,通过对不同工业行业进行划分,建立不同行业工业用地土地集约利用水平评价指标体系,应用多因素综合评价模型对开发区内不同行业工业用地集约利用水平进行了测算,揭示其集约利用水平及其差异性,研究结果表明：北票开发区整体工业用地集约利用水平较高,其中纺织业、服装及其他纤维制品制造业和化学原料及化学制品制造业用地集约水平最高,而饮料制造业用地集约利用水平最低。  相似文献

Rheological properties of the upper mantle of Northern Eurasia and nature of regional boundaries according to the data of long-range seismic profiles   总被引：1，自引：0，他引：1  

N.I. Pavlenkova 《Russian Geology and Geophysics》2011,52(9):1016-1027

Deep seismic investigation carried out in Russia in long-range profiles with peaceful nuclear explosions allowed clarifying in details the structure of the upper mantle and the transition zone down to the depth of 700 km within the huge territory of old and young platforms of Northern Eurasia. Variability of horizontal heterogeneity of the upper mantle depending on the depth serves to qualitative estimation of its rheological properties. The upper part of the mantle to the depth of 80–100 km is characterized by the block structure with significant velocity steps of seismic waves at the blocks often divided by deep faults. This is the most rigid part of lithosphere. Below 100 km horizontal heterogeneity is insignificant, i.e., at these depths the substance is more plastic and not capable to retain block structure. On the lithosphere bottom at the depth of 200–250 km plasticity increase is observed as well but the zone of the lower velocities that might have been bound with the area of partial melting (asthenosphere) has not been found. These three layers with different rheological properties are divided by seismic boundaries presented by thin layering zones with alternating higher and lower velocities. At the specified depths any phase boundaries have been distinguished. These thin layering zones are assumed to form due to higher concentration of deep fluids at some levels of depths where mechanical properties and permeability of substance change. Insignificant number of fluids may result in appearance of streaks with partial or film melting at relatively low temperature—to the rise of the weakened zones where subhorizontal shifts are possible. According to seismic data in many world regions seismic boundaries are also observed at the depth of about 100 and 200 km; they may be globally spread. There are signs that areas of xenoliths formation and earthquake concentration, i.e., zones of high deformations, are confined to these depths.  相似文献

A series of environmentalegeological problems have been caused by over-exploitation of deep groundwater (i.e., confined aquifer water) in the North China Plain. In order to better understand the status of deep groundwater over-exploitation and the resultant environmentalegeological problems on a regional scale, the over-exploitation of groundwater has been assessed by way of the groundwater exploitation potential coefficient (i.e., the ratio of exploitable amount of deep groundwater to current exploitation), cumulative land subsidence, and long-term average lowering rate of the groundwater table. There is a good correlation among the results calculated by the different methods. On a regional scale, deep groundwater has been over-exploited and there is no further exploitation potential under the current conditions. The groundwater exploitation degree index takes the exploitation in 2003 as the reference for the calculations, so the results mainly reflect the degree of current groundwater exploitation. The results of over-exploitation of deep groundwater obtained by land subsidence data and long-term average rate of depression of the water table mainly reflect environmentalegeological problems caused by exploitation of deep groundwater.  相似文献
