基于历史地图解译的崇州罨画池水系演变研究

用历史地图空间解译法先梳理了清光绪至20世纪80年代崇州城市水系的演变,再结合罨画池相关文献,复原了清康熙、道光、光绪时期罨画池水体形态与体系的演变过程图,并从城市水系与园林兴衰、园林的功能使用、水体形态的系统性三方面归纳总结水系演变特点:1)崇州城市水系促成罨画池的形成,也决定其衰败;2)罨画池从以游赏为主的衙署园林最终变为以纪念为主的公共园林;3)罨画池水体系统性的形成深受园林建设的影响。     

晋北堡寨型村庄的特色挖掘与保护规划实践--以旧广武历史文化名村保护规划为例

山阴县旧广武村位于山西省北部,雁门关以北地区,村庄具有典型的晋北堡寨型村庄的军事防御特色。规划根据堡寨型村庄军事设施布局特色,构建以区域控制为主,整体格局保护与分级保护相结合的综合保护体系,以恢复堡寨军事特色风貌为目标,构建完善的用地、道路系统,调整村庄建筑肌理,控制建设区域,恢复长城军堡内外结合、驻防统一、多层次的军事防御体系。研究对晋北地区长城沿线大量类似村镇的保护与发展都具有相应的参考意义。

The Dune Lakes in central coastal California: Why are they dry?

The Dune Lakes comprise 10 natural lakes in the Callender Dunes in central coastal California, USA. These lakes are wetlands in an arid environment, being important habitat for native wildlife and plants, including three occurrences of the federally endangered/State threatened wetland plant, La Graciosa thistle (Cirsium scariosum var. loncholepis; Asteraceae). This plant is known from 21 occurrences, of which only five are extant in 2019. One extant occurrence persists at the lakes and where two other occurrences are likely extirpated. Nine lakes have recently dried, one having been dry for 5 years (2012–2017). Understanding the hydrology of the Dune Lakes is essential for conservation planning and to help prevent extinction of La Graciosa thistle. The best available information points to a combination of two primary causes for drying of the lakes. The first is extensive groundwater extraction beneath Nipomo Mesa to the east. The second is severe drought. The competing demands for water and continued development on the mesa will be obstacles to restoration of the lakes and to recovery of the endangered plant.     

Paradigm shift to enhanced water supply planning through augmented grids,scarcity pricing and adaptive factory water: A system dynamics approach

This paper details a system dynamics model developed to simulate proposed changes to water governance through the integration of supply, demand and asset management processes. To effectively accomplish this, interconnected feedback loops in tariff structures, demand levels and financing capacity are included in the model design, representing the first comprehensive life-cycle modelling of potable water systems. A number of scenarios were applied to Australia's populated South-east Queensland region, demonstrating that introducing temporary drought pricing (i.e. progressive water prices set inverse with availability), in conjunction with supply augmentation through rain-independent sources, is capable of efficiently providing water security in the future. Modelling demonstrated that this alternative tariff structure reduced demand in scarcity periods thereby preserving supply, whilst revenues are maintained to build new water supply infrastructure. In addition to exploring alternative tariffs, the potential benefits of using adaptive pressure-retarded osmosis desalination plants for both potable water and power generation was explored. This operation of these plants for power production, when they would otherwise be idle, shows promise in reducing their net energy and carbon footprints. Stakeholders in industry, government and academia were engaged in model development and validation. The constructed model displays how water resource systems can be reorganised to cope with systemic change and uncertainty.
