【摘要】：边缘效应是生态学的重要研究理论,其对于以人居环境品质提升为目标的城乡规划具有一定的借鉴和指导作用。本文通过富春江中段乡村地区生态边缘区范围和边缘型村庄的判定,提出了生态边缘区域的土地利用优化策略,并以桐庐县梅蓉村为例进行实证。研究利用遥感和地理信息系统等技术方法,通过归一化植被指数NDVI的区域变化特征,发现富春江中段桐庐与富阳的河谷平原地区,存在较为明显的生态边缘效应。其中河流—平原生态边缘区宽度为1KM,山地—平原生态边缘区宽度为1.6KM。区域的生态边缘效应是在富春江沿岸丰富的自然生态要素以及密集人类生产建设活动共同影响形成的,体现了河谷地区特有的生态和社会属性。为了维持富春江河谷平原地区的生态边缘效应,合理引导开发建设和保护生态资源,需要对生态边缘区开展土地利用优化,保持其相对较高的生态环境效益。研究通过对边缘区内不同类型土地单元特征及其相互关系的总结归纳,提出了相应的土地利用格局优化策略。最后以桐庐县梅蓉村为案例,结合梅蓉村自身的土地利用特征和问题,提出细化的土地利用优化方案,在空间上得到相应的落实,实现了理论与实践的结合。
[Abstract]:The edge effect is an important theory of ecology, which has certain reference and guidance for the goal of improving the quality of living environment of urban and rural planning. Through the determination of ecological edge area and edge type village in middle part of the Fuchun River rural areas, put forward the optimization strategy of land use ecological edge region, and in Tonglu County Rongcun Mei as an example.
Study on the use of remote sensing and geographic information system technology, through the regional variation of normalized difference vegetation index NDVI, found in the Fuchun River and Fuyang in the Tonglu River Valley area, ecological edge effect is more obvious. The width of the river - plain ecological edge region is 1KM, the width of a mountain plain ecological edge region for ecological edge effect 1.6KM. is the natural ecological elements along the coast of the Fuchun River rich and intensive human activities affected the formation of production and construction, reflects the social and ecological attributes of valley area unique.
In order to maintain the ecological edge effect of the the Fuchun River River Valley area, a reasonable guide the development of the construction and protection of ecological resources, to the optimization of land use on Ecological fringe development, maintain its relatively high ecological benefit. Through the study on the marginal region of different types of land element characteristics and relationship of the summary, and put forward the corresponding land use the pattern of optimization strategy. Finally, taking Tonglu County as the case may Rongcun, combined with the characteristics of land use and its Rongcun Mei proposed land use optimization programs, refinement of the corresponding implementation in space, realize the combination of theory and practice.
