The effects of land use and its patterns on soil properties in a small catchment of the Loess Plateau

Due to relatively strong human activities in the hilly area of Loess Plateau,the natural vegetation has been destroyed,and landscape pattern based on agricultural land matrix was land use mosaic composing of shrub land,grassland,woolland and orchard.This pattern has an important effect on soil moisture and soil nutrients.The Danangou catchment,a typical small catchment,was selected to study the effects of land use and its patterns on soil moisture and nutrients in this paper.The results are as follows:The comparisons of soil moisture among seven land uses for wet year and dry year were performed:(1)the average of soil moisture content for whole catchment was 12.11% in wet year,while it was 9.37% in dry year;(2)soil moisture among seven land uses was significantly different in dry year,but not in wet year;(3) form wet year to dry year,the profile type of soil moisture changed from decreasing type to fluctuation-type and from fluctuant type to increasing type;(4)the increasing trend in soil moisture from the top to foot of hillslope occurred in simple land use along slope,while complicated distribution of soil moisture was observed in multiple land uses along slope.The relationships between soil nutrients and land uses and landscape positions were analysed:(1)five nutrient contents of soil organic matter(SOM),total N(TN),available N(AN),total P(TP) and available P(AP) in hilly area were lower than that in other areas.SOM content was less than 1%,TN content less than 0.07%,and TP fallow land and cropland,and higher level in soil fertility was found in crop-fruit intercropping land among croplands;(3)soil nutrient distribution and responses to landscape positions were variable depending on slope and the location of land use types.     

医疗废物焚烧残余物固化技术初探

根据对医疗废物焚烧残余物中有毒有害物质的化验分析结果,确定焚烧残余物中有毒有害成分含量仍较高,部分指标超出标准值,必须对其进行稳定化/固化处理,避免对土壤及地下水环境造成污染.本文阐述了稳定化/固化处理原理及处理工艺,使医疗废物无害化、减量化和资源化的处理原则得以全面实现.     

淮河流域水污染防治工作的现状和几点建议

淮河流域是沿淮数百万群众的饮用水源，也是国家重点水利工程——南水北调东线工程的重要输水线路。为了解淮河流域水污染防治情况，近日有关人员赴河南、安徽和江苏三省进行了调研。沿途与环保、水利部门及有关地市政府领导和企业负责人进行了座谈，实地查看了有关河流断面水质状况和企业污染治理设施运营情况，对淮河流域水污染防治工作的现状和问题作了初步分析，并提出几点对策建议。     

医疗废物非焚烧处理技术应用及发展趋势探讨

本文结合美国、欧洲等发达国家和地区在医疗废物非焚烧处置技术方面的具体做法，在对国内外主要的医疗废物非焚烧处理技术进行介绍和分析的基础上，结合国外非焚烧处理技术的应用背景及中国实施危险废物和医疗废物处置设施建设规划，对非焚烧处理技术在中国的应用从技术及管理角度提出了相应的建议。     

医疗垃圾集中处置建设项目的环境影响评价

医疗废物集中处理设施建设项目环境影响评价的程序与一般项目的环境影响评价的程序在评价重点、评价范围及评价内容的确定有着本质的不同，本文针对医疗废物集中处理设施建设项目的环境影响评价的特点及减少这些影响的措施作浅要的论述。     

福州CRT产业集群废物产生特征及管理模式研究

根据对福州开发区阴离子射线管(CRT)产业集群进行调查、访谈和统计分析,实证研究了该产业集群的废物产生特征和管理模式.结果发现,福州CRT产业集群在不断发展壮大的同时,随着主导产品生产规模的扩大以及配套企业的进入,废物的产生总量不断增加,单位主导产品的废物产生强度持续上升,废物种类也逐渐丰富,给区域环境带来的压力不断增大;但同时,产业集群借助其规模和集聚效应,不仅为废物交换和工业共生体系的构建提供了基础平台,而且为专营性废物回收组织和处理处置设施的良好运转营造了外部环境.
