This article is the third in a series prepared to explain the Teller County growth management planning process. Once it was
determined by local decision-makers that Teller County, Colorado, would pursue a policy of directed growth, concepts based
on this policy were developed. These concepts presented visions and options for the future. Landscape plans then were developed
for Teller County and the City of Woodland Park planning area so that these options could be visualized by local leaders and
the public. The landscape plans were used as part of the ongoing citizen involvement process to inform the public about the
options for growth management. To provide even more information, detailed designs were developed for specific areas in the
county. From the landscape plan, public involvement effort, and detailed designs, specific implementation measures were identified,
discussed, and adopted. These measures included guidelines for administration, so that county and city goals could be linked
to the actual day-to-day management of development proposals.

The United Kingdom offers some of the finest designed parks and garden landscapes in the world and, whilst there is a wide range of skills and a wealth of literature on the subject, there is little evidence of official effort to systematically record historic sites. This, it is argued, is a factor in the continuing decline of many examples. This paper records an attempt at a comprehensive examination of one county — Cheshire — begun in 1970. The method is described and the results discussed in some detail. Some suggestions are put forward for improvements to official incentives for site owners. 相似文献

The value placed by the public on the nation's rural landscapes is emphasised by vociferous criticism of insensitive, large‐scale afforestation. As forestry causes massive changes in the landscape in the short term, with results that last for decades, the opportunity provided to improve and conserve should be positively grasped. There is evidence that concensus exists over a considerable part of landscape and design, and this paper explores some of the major factors in landscape design which are consistently important in forest landscapes. 相似文献

城市快速路景观影响评价方法探讨 总被引:2,自引:0,他引:2
首先介绍了国内外道路景观影响评价发展状况和意义,给出了城市快速路景观及视觉影响评价的基本概念、步骤和方针;结合常用的景观影响评价方法,充分考虑工程实践中时间性、准确性要求形成了一套具有较强操作性的景观影响评价方法。在该方法中对指标的概念和标准化处理方法做了改进,计算函数更为实用和完备,并充分考虑了公众关注度的因素,体现了观念的更新。最后给出了对视觉影响的缓解措施和改进意见。 相似文献

甘肃省土壤农业水文特性的研究 总被引:9,自引:0,他引:9
本文在研究甘肃省土壤容重、土壤凋萎湿度和田间持水量的时空分布规律及其相关因素的基础上,根据占田间持水量40%(严重干旱)、60%(轻度干旱)和80%(最适宜)时的土壤湿度标准,计算出5种地域类型26个代表点的不同土壤湿度标准的土壤水分界限值,为各地采取不同的农业耕作和管理措施提供依据。最后以凋萎湿度为主导指标,以容重和田间持水量为辅助指标,建立甘肃省土壤农业水文特性分区指标系统,把全省划分为5个大区12个副区,对各大区土壤农业水文特性值进行了评述,并提出土壤改良措施和相应的办法。 相似文献

Structurally complex landscapes may enhance local species richness and interactions, which is possibly due to a higher species pool in complex landscapes. This hypothesis was tested using cereal aphid parasitoids (Hymenoptera, Aphidiidae) by comparing 12 winter wheat fields in structurally complex landscapes (>50% semi-natural habitats; n = 6) and structurally simple landscapes dominated by agricultural lands (>80% arable land; n = 6). Surprisingly, landscape structural complexity had no effect on aphid parasitoid species diversity. In complex landscapes 12 and in simple landscapes 11 species were found; 9 species occurred in both landscape types. Hence, arable fields in high-intensity agricultural landscapes with little non-crop area can support a similar diversity of cereal aphid parasitoids as structurally complex landscapes. This finding suggests that cereal aphid parasitoids may find necessary resources even in simple landscapes, making generalisations concerning the relationship between landscape composition and biodiversity in arable fields difficult. 相似文献
