胶东“玲珑-焦家式”金矿资源潜力与找矿

“玲珑焦家式”金矿的成岩成矿,从新太古代至中生代存在着继承性的成因关系,成矿具有长期性、多源性特点,但中生代燕山早期岩浆活动是主导成矿因素。区域化探成果显示胶东金矿直接矿源岩———郭家岭花岗岩金的丰度比原始矿源岩———早前寒武纪变质沉积岩系及侵入岩系金的丰度低1/2。郭家岭花岗岩面积在2 km2以上岩体定量估计金亏损总量与胶东金矿总量预测的资源量相当,从一个侧面展现了胶东金矿资源的潜力。望儿山金矿的找矿实践展示,焦家式金矿在1 000 m以下尚有巨大潜力,整个胶东金矿产区在3 000 m以上的资源潜力应在5000 t以上。     

我国个人所得税制度完善的法律思考

个人所得税是与每个人联系都很紧密的税种,它的完善与否,直接体现了我国法制建设的完善程度及居民素质的高低。但现行税制由于内外原因,存在各种缺陷。因此有必要在理论中找到对策,并在实践中寻求答案逐步完善个人所得税制度。     

威海市五项措施抓好温泉资源开发

威海市温泉资源丰富，山东省已发现的18处温泉中。威海占有9处，为搞好温泉资源开发，威海市采取5项措施。提高温泉资源开发利用水平。①强化温泉资源开发审批。严格地热井的审批。对原有低效的地热开发设备进行升级改造，降低资源浪费损耗；对新开发单位。在申请前要制定综合开发方案，达不到要求的不予审批；要变零星审批、单井开发为统一规划、分区块连片开发、多井联网梯级利用。

ANALYSIS OF DRIVING FORCES ON THE CHANGE OF HISTORICAL FARMLAND USE IN SHANDONG PROVINCE DURING THE QING DYNASTY （1644-1911）

How land-cover has been changed by human use over the last 300 years is one of the five overarching questions guiding the Land-use/Cover Change (LUCC) Science/Research Plan. China has variety of historical docu-ments providing unique data superiority. So the characteristics of farmland area in Shandong Province during the Qing Dynasty (1644-1911) are summarized firstly: 1) the rising trend of farmland area was striking; 2) farmland area had re-markable fluctuation; 3) farmland area per capita decreased dramatically; 4) wasteland reclamation index increased rapidly. Then, the driving forces of farmland area change are analyzed. It is concluded that natural and human factors are jointly influential. Among the driving forces, human dimensions are the main factors of farmland area change,which direct the general tendency of the changes mentioned above. And the natural factors influence the stability of farmland area as well. Variation of the natural factors would act as the major contributory factor to farmland area change during years or periods of abrupt climatic changes, or during the intensive occurring periods of natural hazards.Besides, the passive aspects of human factors, such as war chaos also influenced the fluctuation of the farmland area.This research indicates that it is feasible to study the land-use/cover change by Chinese historical literatures, which has huge potential to provide a comprehensive picture of the growing dominance of human land-use and land-cover pat-terns that can be used in many global change research oroiects.     

土地收益金和土地收益能否混为一谈

近几年,在国土资源管理部门征收国有土地租赁租金(俗称年租金)过程中,有不少地市同房管部门征收的出租门面房土地收益金“撞车”,它不仅造成同一种费用重复征收,加重用地单位的负担,损害政府形象,而且形成多头管理土地,使土地资产大量流失,甚至导致不安定因素的发生。造成此种现象的主要原因,虽然是某些部门的职能越位和错位,但是概念混淆、政策打架也是其原因之一。因此,要解决此问题,首先要弄清“土地收益金”和“土地收益”二者的概念。 让我们来看一下房管部门征收“土地收益金”的主要依据,它是根据建设部(1995)第42号令《城市房屋…
