An Approach for Recreation Suitability Analysis to Recreation Planning in Gölcük Nature Park

Gölcük Nature Park (GNP) is an area protected by law in Turkey. It is an important nature park with rich flora, fauna, geomorphologic forms, landscape features, and recreational potential in the region. However, GNP does not have a recreation management plan. The purpose of this study was to determine the actual natural, cultural, and visual resources of GNP, determine the most suitable recreational sites with multiple factors, evaluate the demands and tendencies of visitors, and suggest recreational activities and facilities for the most suitable sites of GNP. However, it was also conceived as leading to a recreational plan and design of GNP in the future and identifying the entire appropriate and current data of GNP with the creation of various maps. This study used multifactor analysis to determine the most suitable recreation sites of GNP. Used recreation factors were established including degree of slope, proximity to water resources, accessibility, elevation, vegetation, soil, climate, aspect, current cultural facilities, visual values, and some limiting factors in accordance with the characteristics of GNP. Weighting and suitability values of factors were determined by 30 local expert surveys. All obtained data were evaluated and integrated in the Geographical Information Systems base. Obtained maps were overlapped. Thus, recreational suitability zones map were created manually. However, the demands and behaviours from visitor surveys in GNP were focused on the most suitable recreation sites of the park. Finally, 10% of GNP was identified as the most suitable sites for recreational use. Various recreational facilities and activities (including picnicking, sports facilities and playgrounds, camping sites, walking paths, food and local outlets, etc.) were recommended for nine of the most suitable areas on the proposed recreational map.

典型化工园区大气中挥发性有机物污染调查

对常州市某典型化工园区大气中挥发性有机物(VOCs)污染状况进行了调查。结果表明,该化工园区大气中检出挥发性有机物共有58种,组分有芳香烃、饱和烷烃、卤代烃、烯烃、醛酯类化合物及其他类;苯、甲苯、乙苯、二甲苯为主要挥发性有机污染物,质量浓度为1.0~194μg/m~3;均未超出参考标准的限值。背景点位和园区点位大气中主要ρ总(VOCs)在秋冬季最高,敏感点大气VOCs随季节变化也较为明显;园区T1和T2ρ总(VOCs)年均值高于敏感点位,背景点位年均值最低;园区点位除了汽车尾气排放之外,溶剂的挥发和生产工艺中污染物的排放也增加了大气中苯系物的浓度,同时也对敏感点位和对照点位的大气质量产生了一定的影响。     

工业园区水管理创新研究

随着工业化和城市化进程,中国的水环境和水安全问题凸显。工业园区在中国经济发展过程中贡献突出,但同时也是环境污染特别是水环境污染的重要来源之一。在日益趋严的绿色生态发展政策导向下,园区实施可持续水管理具有重要现实意义和理论价值。研究基于全生命周期思考和系统优化原则,提出园区水管理创新概念模型,包含供(取)水、用水、废水处理、排放、污水再生回用、污泥处理处置及资源化等与水管理相关的关键环节组成的全生命周期园区水管理体系,实现生命周期全过程管理,防范水风险,改善水环境质量。从多利益相关方的角度,协同园区、企业、周边流域三个层面,采用PDCA循环,设计包含水管理问题识别、成因分析、实施对策和绩效考核四部分的园区水管理创新概念、框架及基本流程,制定以园区管理机构和企业为实施主体的全方位园区水污染防治关键行动,以达到园区和企业水资源消耗总量与用水强度双向优化、周边流域源洁流清,实现可持续生态化绿色发展的长期目标。     

漳州市城市公园灰尘重金属来源及健康风险评价

为了探析福建省漳州市公园灰尘重金属的来源以及重金属对人体健康的危害,通过分析其市区主要公园灰尘的六种重金属(Cr、Ni、Cu、Zn、As、Pb)含量,结合多元统计方法和暴露剂量模型进行解析.结果表明:漳州市公园灰尘的Cr、Ni、Cu、Zn、As和Pb平均含量分别为61.74 mg??kg-1、25.20 mg??kg-...     

PMF和RF模型联用的土壤重金属污染来源解析与污染评价：以西北某典型工业园区为例

基于西北某典型工业园区工厂内的地表土壤中7种重金属元素[As、 Cd、 Cu、 Pb、 Hg、 Ni和Cr(Ⅵ)]的含量，分析该工业园区重金属污染特征，并采用潜在生态风险指数和地累积指数法分别进行生态风险和污染评价；利用正定矩阵因子分解(PMF)模型和随机森林(RF)模型进行定量源解析，并结合采样企业排污资料和源排放成分谱经验数据识别特征元素，判定排放源类别.结果表明，园区所有采样点位的重金属均未超过建设用地土壤污染风险管控标准(GB 36600-2018)中第二类建设用地筛选值；但相比当地土壤背景值，除As和Cr以外的5种元素均有不同程度的富集，整体呈轻微污染和中度生态风险(RI=250.04);其中Cd和Hg是该园区的主要风险元素；源解析结果得到5类主要污染源，分别是化石燃料燃烧与化工生产源(33.73%和9.71%,分别为PMF和RF所得源贡献率，下同),自然来源与废渣堆填(32.40%和40.80%)、交通排放(24.49%和48.08%)、燃煤与有色金属冶炼(5.43%和0.11%)以及电镀与矿石冶炼(3.95%和1.30%).两种模型的总体变量模拟效果R²
