Landscape eco-environmental research on littoral zone in China

Littoral zone is a special land/ landscape type. As an important kind of land resource in support, the use of littoral zone is vital to eastern coastal areas in China. And the research on littoral zone relates to the key theory of landscape ecology. Based on the theory of landscape ecology, the littoral zone was divided into four types: mud flat, sand beach, bench, and biological flat. The distribution of each type in China is pointed out. As a typical open system, littoral zone has six landscape ecological characteristics: (1) high sensitivity to disturbance; (2) distinct edge effect; (3) spatial aggregation of natural resources; (4) frequently spatial oscillation; (5) obviously spatial heterogeneity; and (6) noticeably spatial differentiation. Some proposals are also put forward on the land use and development of littoral zone for environmental protection and environmental management.

Landscape ecological assessment and eco-tourism development in the South Dongting Lake Wetland, China

As an important resource and the living environment of mankind, wetland has become gradually a highlight, strongly concerned and intensively studied by scientists and sociologists. The governments in the world and the whole society have been paying more and more attention on it. The Dongting Lake of China is regarded as an internationally important wetland. For a rational development and protection of the wetland, an investigation and studied on its resources and its value to tourism in the South Dongting Lake was conducted, to create an assessment system of the ecological landscapes, and to evaluate qualitatively and quantitatively the value of wetland landscape to the eco-tourism. The results showed that the scenic value of the South Dongting Lake Wetland satisfied the criterion of AAAA grade of China national scenic attraction. The eco-tourism value of the landscape cultures in the South Dongting Lake Wetland was discussed with emphasis. It were formulated that a principle and frame of sustainable exploitation of the wetland landscapes and it was proposed as well that establishing a Wetland Park and developing eco-tourism in the South Dongting Lake. Wetland is a fragile ecosystem with low resistance to the impact of the exploitation. Thus, we must pay intensively attention to the influence of exploitation on the landscape, take the ecological risk in account to employ a right countermeasure and avoid the negative affection.

i-Tree Eco Analysis of Landscape Vegetation on Remediated Areas of Oak Ridge National Laboratory

The Oak Ridge National Laboratory (ORNL) is the largest and most diverse energy, research, and development institution within the Department of Energy (DOE) system in the United States. As such, the site endures constant land development that creates rigorous growing conditions for urban vegetation. Natural resource managers at ORNL recognize that trees are an integral component of the landscape and are interested in characterizing the urban forest and their associated ecosystem services benefits. We evaluated the urban forest structure, quantified ecosystem services and benefits, and estimated economic value of resources using i-Tree Eco at ORNL. While this assessment captured over 1100 landscape trees, the ORNL Natural Resources Management for landscape vegetation can be expanded to include unmanaged landscapes, e.g. riparian areas, greenspace, and other vegetative attributes to increase ecosystem services benefits. Assigning a monetary value to urban forest benefits help to inform decisions about urban forest management, ideally on cost-benefit analysis.

Landscape eco-environment risk assessment of highway in arid area of Xinjiang,China

With the aid of analyses to landscape ecology in the highway region of the arid area in Xinjiang of China, vegetation type, soil type and land-use type were ascertained as environmental factors of highway landscape ecosystem fragility, and seasonal flood, blown-wind sand and alkali-salinization as disaster factors of highway engineering. All items of these factors constitute an objective hierarchy of evaluating landscape ecosystem risk of the highway region in the arid area. The weighted values of the items were determined according to the number of occupied area or length by them against each unit. The area or length was interpreted with the aids of GIS technology and gained by measuring in the highway reconnaissance. The results of the eco-environmental risk assessment of G315 Yitunbulake-Qiemo section in Xinjiang shows that eight units of landscape ecology can be sorted into four categories according to the differences of the fragility indices (Σxiwi) and the disaster indices (Σyiwj).

Analysis on Ecological Adaptability of Hani Village Landscapes in Yuanyang,Yunnan Province

The eco-adaptation of the landscape in Hani villages consists of two stages.The first stage is the ecological selection and adaptation of the landscapes in Hani villages to the natural environment.The forest landscape ecosystem,the architectural landscape ecosystem,and the terraced landscape ecosystem are the concentrated manifestations of meeting production and living needs,adapting to topographic changes,and adapting to climate features.The second stage is the adjustment and improvement of the landscape in Hani villages to the built environment.It is embodied in the establishment of the Mysterious Woods,abundance of plants in the building group,construction of artificial ditches,production of water infrastructures,and abundance of landscape nodes.In the end,Hani villages have experienced a long process of selection,adaptation,improvement and perfection,and gradually formed a harmonious and unified landscape ecosystem.Through field investigation,this paper analyzed the landscapes of Hani villages from the angle of ecological adaptability.It mainly studied the formation causes of the village landscapes as a material carrier,the process of village landscape adapting to natural and built environment,and the inherent ecological significance,which is of imperative and realistic significance to promote the ecological protection and construction of Hani villages.

Green Design and Planning Resolutions for an Eco-Industrial Town: A Case Study of Polluted Industrial Estate in Rayong Province, Thailand

Map Ta Phut was designated for development in national policy as an Eastern Seaboard Industrial Port. It is located in Rayong Province with growing demand from Eastern Seaboard industries and is heavily affected by serious environmental problems as a'pollution control zone'. While the Joint Standing Committee on Commerce, Industry and Banking, representing the national business sector, claimed that the area generated total revenues of 1.1 trillion baht per year, or 11% of Thailand’s gross domestic product, and employed more than 100,000 workers, the declaration of the area as a pollution control zone severely limited investment and business operations. Thus, controversies arose among the investment business sectors, the residential sector (residents have been affected by a decrease in their quality of life and health) and environmental concern sectors. This paper aims to find an efficient and practical mitigation practice to balance the purposes of the industrial port with protection of surrounding communities and natural resources. The author will apply physical design and planning such as the application of “buffer zones”, “greenbelts”, “set-back”, “green corridor”, “green wall” and “protection strips” along with environmental measurements such as the Air Pollution Tolerance Index (APTI), which can be adapted for pollution protection as best practices of landscape architecture.

以小流域为单元的城市水空间体系生态规划方法--以州河小流域内的达州市经开区为例

当前城市水空间体系规划,多以人为划分的行政管理区域为系统单元展开,与自然条件下所形成的水文生态系统单元的尺度不对等、边界不整合,导致规划成果不能体现自然水文生态系统的整体性和层次性。针对上述问题,研究提出将小流域单元作为城市水空间研究与管理的最佳地域尺度;并在厘清小流域生态水文过程的基础上,将城市小流域划分为小流域、次小流域和集水区等层次,以此建构出完整的水系和湿地空间体系;最后,以州河小流域内的达州市经开区为例,对该方法进行验证。本研究有助于为城市水安全、水生态、水环境、水资源等问题的综合求解,提供因循水文过程、契合自然生态环境的物质空间保障,为城市水空间系统化、生态化建设提供思路。
