试论红色旅游开发中红色旧址的保护和利用——以江西玉山下镇池头墩村为例

玉山下镇池头墩村姜献华家是上饶集中营秘密党组织建立的唯一的一个接应越狱志士的接应点,这里有姜献华等越狱志士组织的在抗日战争时期上饶唯一的一支由共产党领导的浙赣边区抗日游击大队,这里有许多红色资源旧址,但一直没有被有效保护。本文对该地的红色旅游资源的历史背景、现状、保护和开发等方面进行了一系列的探索。

温州教玩具业蓬勃向上势能足

温州教玩具产业主要集中在永嘉县,其中以桥下镇最为集中,自上世纪70年代以来,经过近四十年的发展,已成为全国教玩具产业的重要产销基地和永嘉县四大支柱产业之一。同时,随着中国教玩具之都、中国教玩具出口基地、浙江省教玩具品牌基地、浙江省行业信用基地等称号相继落户桥下镇,桥下教玩具的知名度与日俱增。

Integrated evaluation system under randomness and fuzziness for groundwater contamination risk assessment in a little town, Central China

An integrated evaluation system under randomness and fuzziness was developed in this work to systematically assess the risk of groundwater contamination in a little town, Central China. In this system, randomness of the parameters and the fuzziness of the risk were considered simultaneously, and the exceeding standard probability of contamination and human health risk due to the contamination were integrated. The contamination risk was defined as a combination of "vulnerability" and "hazard". To calculate the value of "vulnerability", pollutant concentration was simulated by MODFLOW with random input variables and a new modified health risk assessment(MRA) model was established to analyze the level of "hazard". The limit concentration based on environmental-guideline and health risk due to manganese were systematically examined to obtain the general risk levels through a fuzzy rule base. The "vulnerability" and "hazard" were divided into five categories of "high", "medium-high", "medium", "low-medium" and "low", respectively. Then, "vulnerability" and "hazard" were firstly combined by integrated evaluation. Compared with the other two scenarios under deterministic methods, the risk obtained in the proposed system is higher. This research illustrated that ignoring of uncertainties in evaluation process might underestimate the risk level.

浙赣边区晚奥陶世地层之新见

浙赣两省交界的三山地区（江山、常山、玉山）晚奥陶世Ａｓｈｇｉｌｌ中期的海相沉积主要包括３种岩相：碳酸盐岩相的三衢山组、碎屑岩相的长坞组以及碳酸盐岩和碎屑岩交互相的下镇组；这３种类型的地层在研究区内的横向分布存在一定规律，即从西南至东北大致为下镇组、三衢山组和长坞组。经详细的生物地层和岩石地层研究，建议取消“大桥灰岩”一名，用“下镇组”代替；整合于三衢山组之上的“文昌组”不宜归为Ａｓｈｇｉｌｌ晚期，仍属Ａｓｈｇｉｌｌ中期的沉积。通过系统的生态地层分析，对研究区内各种岩相地层之间的对比也提出了新的意见。
