四川绵阳出土的西汉饱水漆木器的前期保护工作

为保护四川绵阳出土的西汉饱水漆木器,使用脱水定型法对20件物进行了保护。选用甲醇脱水,十八烷醇加固定型的方法,继而作旧,封护。结果表明,经保护处理的物,其弦向平均收缩率为8％左右,径向平均收缩率为1％左右,说明保护处理是成功的。实验说明,甲醇一十八烷醇脱水定型法具有普遍的推广意义。     

京津冀地区旅游业的碳排放测算与比较研究

本文借鉴"旅游消费剥离系数"概念构建了京津冀地区旅游业碳排放量的计算方法,并对京津冀三省份的旅游碳排放指标进行了比较分析。研究表明:2010-2012年京津冀地区的旅游碳排放总量持续攀升,从591.018万吨增加到696.3万吨,而旅游者的人均碳排放总量持续递减;2010-2012年北京市旅游业碳排放总量均排名首位,河北省始终最低,但是增长势头迅猛;从人均总量对比情况看,2010-2012年河北旅游业碳排放人均总量在京津冀中最低,同时,北京人均总量却是最高的,2010-2012年京津冀地区中只有北京的人均总量逐年下降,天津旅游业碳排放量人均总量呈现倒U型变化特征,而河北呈现持续上升特征。未来京津冀地区需要从节能减排行动纲要制定、企业节能技术创新等方面推进旅游节能减排工作。     

避暑旅游指数概念模型及评价指标体系构建

气候变暖背景下避暑旅游成为夏季旅游市场的主旋律。地方政府及旅游主管部门在培育避暑旅游目的地时应从何入,手旅游者如何能够准确地做出避暑旅游决策等是一个现实问题。本文在综述国内外相关研究与实践的基础上,认为舒适凉爽的夏季气候条件只是避暑旅游的最基本条件,创新性地提出应侧重从产业发展的角度,引入旅游休闲度、游客满意度和综合风险度等指标。避暑旅游评价指标体系的构建为目的地避暑旅游条件评估提供了理论框架,有助于游客准确地做出避暑旅游决策,同时也为目的地避暑旅游发展与提升提供一个具操作性的管理工具。     

生物病害对唐皇城含光门土遗址的危害及防治措施研究

唐皇城含光门土遗址蕴含丰富的历史、文化、科技等多方面的信息,但是随着时间的推移,出现了多种生物病害,急需要抢救保护。通过对土遗址生物病害的详细调查,首次发现螨虫类和鞘翅目昆虫对遗址有强烈破坏作用,同时存在的生物病害主要还有蓝藻和霉菌等。本研究分析了这些生物病害产生的原因及腐蚀土遗址的机理,并进行了防治措施研究。这些调查分析,将对遗址进一步抢救保护打下坚实基础。     

重庆大足石刻舒成岩砂岩本体表面风化产物研究

针对重庆大足舒成岩摩崖造像和岩体富集灰尘部位出现的粉化伴随着层状剥落现象,采用X-射线衍射仪(XRD)、X-射线荧光光谱仪(XRF)、傅里叶变换红外光谱仪(FTIR)、环境扫描电子显微镜(SEM)和X-射线光电子谱(XPS)对岩石、岩体风化产物与灰尘样品进行了组成结构表征研究。研究发现灰尘和有害气体干沉降过程中酸性物质能够导致砂岩中钙质胶结物发生溶解,伴随着各种盐类结晶应力,导致岩石表层发生风化。研究成果为西南地区石窟寺保护提供了重要参考数据。     

Cellular Automata for Studying Historical Spatial Process of Traditional Settlements Based on Gaussian Mixture Model: A Case Study of Qiaoxiang Village in Southern China

ABSTRACT

The spatial evolution of traditional rural settlements is a natural process that occurs without professional development planning. With rural spatial organization now being stimulated by China’s economic structure adjustment, making top-down plans match bottom-up spatial principles is important for the continuity of rural communities. In this research, a Cellular automaton based model was introduced to describe the historical spatial rules of rural settlements based on a traditional village in Southern China. In order to reproduce the rural spatial characteristics and laws that were close to the actual situation truthfully and distinctly, in this model, we refined the growth process into three cyclical steps, and used a Multivariate Gaussian Mixture Model for the evaluation of spatial transition potential. Through historical simulation, evaluation of the current status, and future spatial predictions, results showed that: (1) the growth during the whole spatial process maintained logical consistency for optimal selection; (2) certain houses in the southeast region should be carefully protected as a core living culture exhibit, while the best utilization of other homes should be considered; and (3) the most probable region of growth for tourist services or new housing estates is scattered along the river in the central area of the village.
