自然资源代际转移模型研究

代际均衡发展是可持续发展的核心内容之一，而代际均衡的实现在目前情况下有赖于代际主动财富转移改策实施。政府的宏观调控是实施这一政策的有力手段。具体的措施可开征“资源代际补偿税”以建立专项基金制度     

论环境移民

由于环境恶化，部分区域出现了一种特殊的人口迁移类型－－环境称民。环境移民是人口增长与环境容量之间矛盾的必然结果，本文对环境移民的概念、要素和实质作了初步的探讨。

A novel approach to treat combined domestic wastewater and excess sludge in MBR

Domestic wastewater was treated by combined anaerobic biofilm-aerobic membrane bioreactor(MBR) process, and part biomass in MBR was withdrawn, to treat with ozone, then the ozonated sludge was returned to anaerobic inlet. In aerobic MBR, MLSS and DO were controlled at 3000—3500 mg/L and 0.8 mg/L respectively. Comparing the experimental results of two stages, it was noticed that ozonation did not affect the removal efficiency for organics but had a significant influence on the removals of NHs-N and TN. During the ozonation period of two months, no excess sludge was wasted, and a zero sludge yield was obtained.     

内蒙古流沙山金(钼)矿床地质特征及矿床类型的划分

流沙山矿床是近年来在内蒙古西部发现的一处金 (钼 )矿床。金 (钼 )矿化主要在海西期花岗闪长岩内呈大脉细脉和线脉产出 ,其空间展布形态受一系列环状断裂带控制。金 (钼 )矿体多为环状到半环状透镜体 ,局部地段为扁豆群和楔状体。矿石的金属矿物有辉钼矿、白钨矿、辉铋矿、黄铜矿、黄铁矿、钼钙矿、自然金和银金矿。脉石矿物有石英、钾长石、斜长石、黑云母和角闪石 ,其中辉钼矿Re Os同位素等时线年龄为 (2 6 0±10 )× 10 6a。矿体的围岩蚀变主要有硅化和钾化 (钾长石化和绢云母化 ) ,次为绢英岩化和青盘岩化。本文重点研究了与矿化有关的花岗岩类岩相学和岩石化学 ,阐述了金 (钼 )矿床的矿化特征 ,划分了矿床的蚀变分带。在对比流沙山金 (钼 )矿床与国内外经典性斑岩型金属矿床主要特征的基础上 ,将流沙山 (钼 )矿床确定为深成岩型斑岩金 (钼 )矿床
