政和—大埔断裂带基本特征及其演化模式

政和—大埔断裂带经历多期复杂的构造变形变质作用,不同地段的时空演化特征有所差异,总体上可划分为四个演化阶段。即:①前加里东期(?)—加里东期韧性剪切变形变质作用(D_1),发生于中、下地壳,是顺层剪切(固态流变)的结果,为纯韧性变形,②印支期韧性剪切变形变质作用(D_2)——政和—大埔断裂的形成,以平移型剪切为主,形成S——C糜棱岩,为半韧性变形环境;③印支末期—燕山早期逆冲—推覆作用(D_3),为多层次逆冲推覆,东部所谓的“天窗”部分为这一时期逆冲岩片的残留体,随着早燕山期花岗岩的侵入逐渐过渡到伸展拆离环境,同时西部推覆体后缘出现拉张,形成有限的火山岩盆地,为半脆性—脆性变形环境;④燕山期(—喜山期)伸展—拆离作用(D_4),在相对年轻的拆离断层之下出露变质核杂岩(如稻香组和熊山岩体),并形成裂陷盆地堆积(梨山组),东部部分“天窗”属这类成因,形成环境跨度大,为半韧性→半脆性→脆性。     

A regional environmental management information system for Chinese EPA—the system analysis and design

REMIS is one of key research projects sponsored by the central government. It is recommended to regional EPAs as a main tool of the environmental management. REMIS simulates the functions of the regional EPAs and aimed to improve their management level. The national environmental management information system will base on REMIS.Functional analysis is the kernel of the REMIS system analysis. Data and data flow analysis are used to support the functional analysis.Investigations on the functions of the local EPAs of eight provinces and 12 cities have been taken. The functions were carefully sorted. Modular design method was used in system analysis and system design.The system analysis included functional analysis, data analysis and data flow analysis. The system design is based on the system analysis. HIPO diagram of each modular, data base structure, menu design, selection of hardware and software environment were the main items of the system design.

SO2和氟化物对农作物的危害的鉴别与防治

SO2 和氟化物对农作物的危害可通过症状、镜检和受害叶片的化学分析来鉴别 ,并从风向、与污染源距离、障碍物和叶片成熟程度几方面与作物病虫等影响因素相区别。排放浓度、接触时和作物本身抗性是影响危害程度的主要因素。应从治理污染、选种抗性强树木、避开作物敏感生育期、合理种植、加强施肥等方面采取措施加以防治     

海南省旅游地评价及其开发研究

旅游地资源评价和开发研究，是进行旅游开发宏观决策，确定对应的旅游活动类型和接待规模，指导旅游市场开发与景区、景点设计时一项重要的基础研究工作。本文以海南省为例，对旅游地资源的评价制图和旅游开发用地预测方法，进行了有益的探讨。     

江苏省盐城市环境空气质量综合评价及整治对策

随着经济发展的加速,盐城已逐步融入长三角经济体系中,城市现代化建设正在大踏步向前迈进,城市生态环境问题也日益受到关注,生态环境问题已成为社会关注的焦点,是衡量盐城社会经济发展的重要指标,实现环境、经济、社会的和谐发展已逐步成为人们的共识.文章针对盐城环境空气质量问题,运用SO2、NO2和PM10等指标表示空气环境质量,采用模糊综合评价方法对盐城空气环境质量等级进行了划分,并采用API指数评价方法对污染程度作出了评价,分析了盐城环境空气质量面临的挑战,提出了盐城市区污染的防控措施.

Influence of glucose feeding on the ligninolytic enzyme production of the white-rot fungus Phanerochaete chrysosporium

The present work studied the influence of glucose feeding on the ligninolytic enzyme production of Phanerochaete chrysosporium in a nitrogen-limited (C/N ratio is 56/8.8 mmol/L) medium. Several sets of shaking flask experiments were conducted. The results showed that 2 g/L glucose feeding on the first day of the culture (24 h after the inoculation) simulated both fungal biomass growth and enzyme production. The manganese peroxidase (MnP) activity was 2.5 times greater than that produced in cultures without glucose feeding. Furthermore, the glucose feeding mode in fed-batch culture was also investigated. Compared to cultures with glucose feeding every 48 h, cultures with glucose feeding of 1.5 g/L (final concentration) every 24 h produced more enzymes. The peak and total yield of MnP activity were 2.7 and 3 times greater compared to the contrast culture, respectively, and the enzyme was kept stable for 4 days with an activity of over 200 U/L.

四川锦屏山地区部分地层时代、玄武岩和花岗岩地球化学特征及构造环境

锦屏地区的地质研究程度较低，部分地层时代争议较大，玄武岩、花岗岩的性质、物质来源和构造环境等尚未深入研究。为了切实评价区域稳定性，基础地质研究十分重要。通过同位素年代学和孢粉分析，改盐塘组时代由中三叠世为早二叠世，皮罗渡桥西黑色砂页岩层为晚三叠世；稀土元素、过渡元素、微量元素和岩石化学分析表明，在金一箐断裂东西两侧分布的玄武岩为上地幔来源、不同于陆海环境的大陆裂谷喷发产物，花岗岩的分异和重熔程度不同，代表造山期挤压向造山期后拉张环境转化。上述结论为该区构造发展演化和区域稳定性评价、矿产资源寻找提供了重要基础资料。
