From natural environment to artificial system: Chang'an and its water system in the Western Han Dynasty

People around the world have shaped societies and urban spaces around water for millennia. They have transformed natural water structures and patterns to serve their diverse needs. The ways in which historical decisions affect contemporary water systems and influence future planning of urban systems still need to be fully recognized. This paper explores the multiple roles of water systems in Chang'an during the Western Han Dynasty. Chang’an, one of the ancient names for the city of Xi’an, was a typical capital city of China and East Asia in early ancient times. This study explores everyday practices pertaining to water as well as its role in defense, gardening, politics and culture.Drawing upon three historical theories, this study presents findings that water was embedded in the design of traditional Chinese capitals. The siting and construction of capital cities was first based on the Theory of Choosing the Center (3rd century BCE) and the Theory of Conforming to Nature (5th–3rd century BCE). However, the final maturation of this urban morphology, including the water system, was closely related to the Theory of Symbolizing and Modeling Heaven and Earth (4th–3rd century BCE), in a way that manifested the imperial power's organization and control of space and time.Through close analysis of historical documents, archaeological reports and modern investigations, the paper aims to clarify, analyze and summarize the historical context and evolution, functional and structural characteristics, as well as the economic, political, cultural and military connotations of water systems in Chang'an. It argues that the coordination of urban construction and the water environment was a key foundation for capital city development. It proposes that people shaped urban water supply in many ways, including daily life, waterway transportation, agricultural irrigation, aquaculture promotion, military defense and fire prevention.The water system in Chang'an also provided an important place for royalty and nobility to go fishing, to hunt and to engage in leisure and naval training. The landscape with this water system as the core, including Taiye Lake and Kunming Lake, had also inspired Chinese gardening history, and had a profound impact on future generations. More importantly, the capital's urban morphology design was a miniature of the world recognized by the monarch, as well as the symbolic image of the supreme rulers' political and cultural desire to control and possess Tianxia, which essentially means the whole world. In conclusion, the paper calls for a closer study of water-based design as a foundation for urban planning.     

昆明市抗战遗址现状与保护利用思考

昆明市抗日战争遗址主要是指中国人民在抗日战争期间经过战争或用于战争遗留在昆明市区内的遗址及遗迹,以及为躲避战争搬迁至昆明的外省人士在昆明市区内留下的建筑遗址或遗物。对昆明市区内战争遗址进行考察和梳理,并对这些战争遗址和遗迹资源的深入研究、保护和利用,有利于还原历史,保护文化遗产空间,优化旅游产业配置和地区经济推动,还有助于警示人们铭记历史,珍惜和平。     

基于SBAS-InSAR的昆明地面沉降监测研究

昆明主城区位于滇池以北沉积平坝区,高原湖相沉积软土分布广泛,在荷载作用下容易产生地面沉降。本文利用短基线(SBAS)技术对昆明市主要区域(近900km2)进行大规模的地面沉降研究。实验中采用了17景C波段ENVISAT ASAR雷达影像和9景L波段ALOS PLASAR雷达影像,利用StaMPS软件SBAS算法反演昆明市2007-2010年的地面沉降。两种影像的时间序列分析结果均表明:小板桥、河尾村等沉降中心沉降速率持续上升;三竹营、吴家营、小渔村等新的沉降中心正在形成;吴家营、大塘子、河尾村、小渔村、雨龙村等沉降中心已经连为一体。得出的地面沉降趋势与实地历史水准测量结果较为一致,验证了SBAS技术进行地面沉降监测的可靠性和有效性。

昆明市旅游业综合改革与发展研究

昆明市旅游业历经10年的辉煌之后．出现了“规模增长．地位下降”的尴尬态势。出现这一现象的主要原因是21世纪旅游业的核心竞争力不仅仅是传统的旅游要素,而是更倚重于现代旅游要素。昆明与新兴旅游城市的差距就在于现代旅游要素的相对稀缺。昆明已经进入到“项目驱动发展”、“竞合激烈”、“危机并存”的旅游发展时代．为防止目的地继续老化和衰退,昆明应该借东南亚作为昆明旅游和加快旅游增长要素的转变,深度改革和发展旅游产业．建设和创新旅游品牌、产品和项目．改革和创新旅游管理服务机制和体制,方能重塑旅游辉煌．再续旅游神话。     

控制滇池生态环境的关键

滇池水污染、生态恶化 ,近 10年综合治理仍未能逆转。认为导致滇池生态恶化的原因主要有三方面 :一是入湖污染物量超过水环境承载能力 ,水污染和水体富营养化 ;二是城市发展超过水资源承载能力 ,难以保证生态环境用水 ;三是滇池逐步演化成半封闭湖泊 ,加上数十年污染负荷剧增 ,加速了生态环境变化由量变到质变的进程。改善滇池生态环境的关键措施有 :综合治理 ,有效控制污染物 ;引水济昆 ,缓解流域水资源匮乏 ,从根本上提高滇池流域水资源及水环境承载能力。
