环渤海地区土地利用变化的驱动力分析

1985到1995年间,环渤海地区占总面积30%的土地发生了利用方式的变化,耕地变化是其核心类型。耕地变化的主要流向依次为农村居住用地、林草地、城市居住建设用地以及果园和水域。本文通过对耕地流向及其与人口变化、农业经济发展的关系等进行分析,确认土地管理政策、人均居住用地的增长、农业生产结构调整以及城市扩张是该区土地利用变化的主要驱动因素

The Source System of Mesozoic Magmatism in Middle and Lower Yangtze Valleys and Adjacent Areas—A Geochemical Tracer Study

The mechanism that controls regional mineralization must be governed by a series of geochemical reactions in relation to the source system of magmatism.In this respect,the geological bodies must have been overprinted by various kinds of tracers in terms of either chemical elements or isotopes.For this reason,the problem may be better approached by treating the lithosphere as a whole with due considerations given to the various tracer elements and isotopes and the various media of the magmatism(magmatic as well as sedimentary rocks).Presented in this paper are the results of this attempt based on a great wealth of available data concerning the source system of Mesozoic magmatism in the Middle and Lower Yangtze Valleys and adjacent areas.     

甘肃西部及邻区区域地质特征与油气勘探方向

按板块构造观点，甘肃西部及邻区可划为中部华北—塔里木板块、北部兴蒙—天山板块和南部祁连—阿尔金板块３个一级、６个二级和９个三级构造单元。依基底性质可分为前寒武纪结晶基底和古生代褶皱基底两大类６个区。区内中新生界盆地有４种类型：陆内裂谷盆地、碰撞带内裂谷盆地、山前裂谷盆地和碰撞带内压性盆地。石炭—二叠系、侏罗系和白垩系为本区油气勘探主要目的层，随盆地的发育成为不同的有利勘探目标与方向。     

河北省山区持续发展的问题与对策

Mapping radon-prone areas - a geophysical approach

 Radon-prone areas in Israel were mapped on the basis of direct measurements of radon (²²²Rn) in the soil/rock gas of all exposed geological units, supported by the accumulated knowledge of local stratigraphy and sub-surface geology. Measurements were carried out by a modified alpha-track detection system, resulting in high radon levels mainly in rocks of the Senonian-Paleocene-aged Mount Scopus Group, comprised of chert-bearing marly chalks, rich in phosphorite which acts as the major uranium source. Issues of source depth, seasonal variations and comparison with indoor radon levels are addressed as well. This approach could be applied to other similar terrains, especially the Mediterranean Phosphate Belt.     

县级山区月平均气温推算方法

本文根据山区月乎均气温形成的主要物理过程,提出以海拔高度、坡地太阳总辐射、地形动力因素为因子的新的月乎均气温推算方法,并以浙江龙泉山区为例进行拟合和计算。经检验,平均拟合误差为0.2℃,最大误差不超过0.4℃。
