Responses of spatial-temporal variation of Karst ecosystem service values to landscape pattern in northwest of Guangxi,China

The responses of spatiotemporal variation of ecosystem service values (ESVs) to landscape pattern from 1985 to 2005 in a typical Karst area of the northwest Guangxi Zhuang Autonomous Region,China,were examined us-ing remote sensing and geographic information system techniques in this paper.The total ecosystem service values de-clined significantly from 1985 to 1990,and then increased slowly from 1990 to 2005,almost equaled to the 1985 level.The ecosystem service values tended to decline from the west to the...     

Changes of residential land density and spatial pattern from 1989 to 2004 in Jinan City,China

Urban sprawl is driven by a myriad of factors, the predominant one of which is the development of residential land. Selecting part of Jinan City for a case study, we use the landscape metric of percent of landscape (PLAND) to capture residential land growth and density changes in 1989, 1996 and 2004 to illuminate the dynamic process of residential land development. The results indicate that the moving window method and the landscape metrics method are efficient ways to describe residential land density. The residential land showed the greatest change among the built-up land with 1995.68 ha from 1989 to 2004, which is mainly transformed from agriculture land and green space. The urban center area of study area is primarily covered with medium density residential land, and surrounded by high density residential land. The development pattern of residential land exhibited both fill-in (new growth occurs through infilling the free spaces within the developed area) and sprawl processes, influenced by a series of factors, such as urban development policy, conservation of springs, recreational and aesthetic amenities. The findings of the study will help to guide urban planning with a focus on the management and protection of the environment and resources.

景观生态学教学的短期户外观摩：云南大学的实践

景观生态学研究的社会认知度在不断提高,教学研讨却相当滞后。介绍云南大学的景观生态学教学实践和经验,以期抛砖引玉。云南大学的景观生态学教学始于1987年,至今在本科、硕士、博士3个层次上开展不同深度的授课。为期1～2天的短期户外观摩,是课堂教学的组成部分,分3个步骤：（1）行前利用Google Earth网络资源演示预设线路和地点的景观结构和生态过程,激发学生的求知欲望;（2）围绕河流-湖泊污染扩散、越冬红嘴鸥觅食-安全日迁移两种生态流实施户外观摩教学,使学生在现实景观里理解和识别景观基底-廊道-斑块、源汇景观转换、景观边界及边缘效应等书本知识;（3）强化总结讨论,促使户外观摩印象的理论升华。

喀斯特地区土地整理景观生态规划与设计--以贵州荔波土地整理项目为例

土地整理是对土地资源及其利用方式的再组织和再优化过程,改变了土地利用类型和空间结构,必然引起景观格局和生态过程的变化,土地整理的景观生态保护研究尤其是在生态脆弱的喀斯特地区显得尤为重要与迫切。景观生态规划设计能有效促进生态系统的保护与恢复,土地整理融入景观生态规划设计思想是未来土地整理的重要发展趋势之一。本文基于景观生态规划与设计的思想,探讨了土地整理景观生态规划设计要点,以贵州省荔波县板寨河头土地整理项目为例,进行了农田斑块、农田水利工程、道路工程和生物多样性保护工程的景观规划设计,促进自然景观和生物多样性的保护,为土地整理的规划设计和生态环境影响评价的实践工作提供科学依据。     

河北省天桂山典型溶洞景观成因类型

河北省天桂山地区的喀斯特洞穴集中分布在早古生代寒武纪-奥陶纪碳酸盐岩地层中,多沿NW-SE、NE-SW和近S-N断裂发育.受第四纪间歇性构造抬升影响,溶洞具有成层分布特点.以溶洞景观类型为基础,将该区溶洞分为侵蚀型和堆积型两大类,分别以银河洞和珍珠洞为代表,前者多发育各种窝穴、流痕、边槽等侵蚀及坍塌景观,后者则发育各种化学堆积景观.研究溶洞景观成因类型及特征对于天桂山旅游资源的合理开发和保护具有重要指导意义.     

龙虎山世界地质公园丹霞地貌成景系统特征及其演化

龙虎山世界地质公园内分布着大量以石寨、石墙、巷谷、峰林、石峰、石柱、石崖、巷谷、一线天、造型石等景观类型,它们形成于晚白垩系龟峰群,是我国典型的丹霞地貌分布区之一.其形成不仅与红层、构造及流水等外营力等构成了丹霞地貌的成景系统因素有关,而且也与它们在信江盆地内的空间位置相关,共同制约着不同位置上丹霞地貌的演化进程及其景观总体特征.     

湿地生态景观的审美价值与旅游开发

湿地生态景观构建以水生态环境为基础,它具有原生态环境、动感生态场景、人文生态内蕴等审美特征。湿地旅游的开发建设要特别强调科学,注重生态与文化的保护,产品要主打生态品牌,营销要突出绿色主题,运行要倡导低碳环保,走绿色低碳发展之路。     

HUMAN MODIFICATION OF KOREAN LANDFORMS FOR GEOMANTIC PURPOSES*

The geomantic idea of chosan pibo is a particular way of remedying the inadequacies of a geomantic landscape by building small mounds of earth or stones and has been a significant motivation for modifying the environment in Korea. This idea is a part of ancient Chinese geomancy, or feng shui, for determining auspicious sites. Historically, three principal geomantic means have been used to compensate for shortcomings at an auspicious site: building religious structures, such as temples; creating hills, planting trees, or changing directions of watercourses; or making other symbolic gestures, such as naming objects and places. In this article I concentrate on the second, modifying landforms to compensate for the geomantic shortcomings of a place. The quasi‐religious zeal shown by feng shui practitioners in Korea to improve the local geomantic landscape is worthy of comparing and contrasting with the European Christian idea, held by medieval monastic monks, that humanity is a partner of God in improving the environment.
