Summary: | 碩士 === 東海大學 === 景觀學系 === 94 === Urban environment is an artificial environment that is interacted and connected by diverse matrix, corridor and patch. Human behavior affected structure easily, it changed with the development of economical, social and ecological elements. As a result of difference between urban space and environment resource, each district of urban aren’t in agreement on development and emphasis to park and green land, in the process of land use changed by human reduced vegetation area, separated surrounding habitat, formed a great many fractal habitat, decreased variety and separated the community of biology, then it will result in destroy completeness and healthiness of original ecosystem. Connectivity is an important feature of landscape network structure that is also the significant factor of regional restored-ecology. In order to promote ecological function of urban environment, a lot of expert and scholar have proposed policy and relative plan of park and green land, utilizing concept of connectivity to construct urban park and green land. The purpose of this study are as follows: (1) applying connectivity viewpoint of landscape ecology to discuss structure connectivity of urban park and green land that is considered as patch in urban environment; (2) selecting birds have apparent and easily-observed migration and assemblages as indicator species to discuss assemblages would be effected by connectivity of urban park and green land or not; (3) to review correlation between functional connectivity and structure connectivity for comprehending the relationship between biological behavior and urban park and green land connectivity; (4) to propose suggestion from results of this study via comprehensive analysis on site, as the consultation for ecological planning and ecological conservation of urban park in the future.
The study applies connectivity viewpoint of landscape ecology to discuss connects of urban park and green land; review correlation between connectivity and avian assemblages via Pearson’s correlation. Thus, in order to improve connectivity of urban park and green land should consider distance between surrounding habitat, distributive form, width of green corridor, and length, etc.; to increase constructing green corridor or street trees to combine the existing urban park and green land, enhancing the connectivity of all park land and consider the forming of surrounding green belt to promote the expression of ecological function.
