Natural links: naturalistic golf courses as wildlife habitat

Worldwide, there are over 25,000 golf courses. In the United States, there are approximately 15,000, with developers building about 350 new courses each year. Japan, Taiwan, China, and other countries are experiencing a similar golf boom. Some developers regard golf course development as one of the fastest growing types of land development in the world. Typically considered by ecologists to be an environmental problem, scientists are now reexamining golf courses to assess their potential to be wildlife habitat. Can naturalistic courses (those with substantial amounts of native wildlife habitat) actually benefit wildlife populations, especially birds, and still be attractive to golfers? My ecological research with a well-known naturalized links-style golf course in Kansas suggests that a naturalistic golf course can support significant numbers of birds, including many threatened species. When compared to a nearby natural area, the golf course equaled the natural area in total bird species richness but not in the relative abundance of specific kinds of birds. Naturalistic golf courses, while not natural areas, can complement biological reserves, military reservations, greenbelts, parks, farms, backyards and other units of the regional habitat mosaic. The large amount of habitat on naturalistic courses also reduces water runoff, irrigation, and chemical inputs. Furthermore, raising the profile of naturally landscaped golf courses can engage thousands of additional people in wildlife habitat preservation issues. Naturalistic courses are growing in popularity and the golfing community is responsive to aesthetic and environmental concerns. With the involvement of ecologists, this burgeoning interest in natural habitats on golf courses may significantly increase the amount of wildlife habitat, especially if designers build these kinds of courses in urban areas and on degraded landscapes such as landfills, quarries, and eroded lands.     

Dynamic earth-contact building: A sustainable low-energy technology

Sustainable development includes low-energy buildings, which reduce energy consumption, green house gases emission, water usage, etc. The choice of subsurface wall at varying depths for construction of buildings has a direct impact on energy consumption and the environment. This paper includes in its scope all building structures in which a significant area is in direct contact with the earth, and excludes indirect earth contact. A two-dimensional simplified analytical Fourier boundary series was developed to study dynamic earth-contact heat transfer and humidity variation in building. It was used in conjunction with the whole-building energy simulation program developed in the TRNSYS environment. The predictions were compared with extensive experimental data measured from typical existing earth-contact buildings situated in the Indian Institute of Technology Delhi campus. Heat transfer through earth-contact building structures was predicted to decrease with increasing soil contact. The results obtained from the detailed model showed that earth-contact structures form excellent passive technology that can be exploited for energy conservation. This work is part of an effort to develop zero energy building models in India. The presented model can be easily incorporated into indirect earth-contact structures in order to describe the impact of cooling tubes, earth-air tunnels or heat pumps in indoor environment.     

基于负荷预测和非支配排序遗传算法的人工相序优化方法

在对0.4 kV配电台区进行节能降损时发现,调整负荷的接入相序能够有效降低台区的线路损耗和三相负荷不平衡度。文中提出基于负荷预测和非支配排序遗传算法(NSGA2)的人工相序优化方法。首先,利用配电台区出口电流曲线替代法建立用户负荷模型。其次,基于历史数据使用Elman神经网络对调相日的台区内各用户日电量和出口三相电流进行预测。然后,基于预测数据综合考虑以线损最低和调相次数最少为目标函数,建立配电台区多目标相序优化数学模型,使用NSGA2对该模型进行求解,得到优化后各负荷接入相序。最后,通过对比安徽电网某配电台区调相前后的理论线损,验证本文所提方法的有效性。     

旧城衰败片区高密度开发改造中的历史保存与延续——以北京大吉片区改造为例

文物引导下的遗产保护制度反思

本文针对“历史文化名城、历史文化街区就是文物”的论调,以及“历史文化名城、历史文化街区的保护必须遵循文物的保护方式与要求”的逻辑结论进行了制度概念层面的反思。认为造成这一论调与结论的原因在于：遗产保护制度变迁下所形成的固化思维模式,导致了文物概念范畴上的谬误,致使历史文化名城、历史文化街区保护等同于文物保护,由此,促使现实中历史文化名城保护、历史文化街区保护以及旧城历史文化遗产保护的乏力。同时,在这种思维引导下,片面单一的保护模式也成为了制度变迁下的产物,并且也是造成“重传统建筑等遗产,而轻城市文化环境”的制度渊源。
