碩士 === 東海大學 === 景觀學系 === 94 === Base on Landscape Ecology Theory, the issue is thought to connect with Natural Ecological Network. Regard Tatu River Mouth as an empirical site, conunted the basic map of Datu River Mouth with GIS, include of 1976(8), 1985(8), 1991(9), 1996(9), 2003(8). To collect the site background, regard Landscape Security Pattern theory as an study method, connected with Neutral Landscape Model and Percolation Theory for an analysis, to supply a reference system for the real landscape, in order to find out the relevant factors about Datu River mouth landscape pattern and process, to construct of the Datu River Mouth Landscape Sceurity Pattern, to provide a consultation for the unit concerned to make the landuse planning, and then control or reduse the behavior of destruction and impact caused toward the environment of human development. This result of study is summed up as follows: 1.Verify the concept with “Landscape Security Pattern”, combine analytical method of “Neutral Landscape Model” and “Percolation Tehory” have concrete and feasible on landscape planning. 2. Chossing “source points” and “strategion points ” is important factors to influence the distribution of landscape ecological corridor. Must only regard scientific real example as foundation for estimating principle. 3.Use GIS to help analysis to Landacape Security Pattern, it’s really to set up a quantization operation model for planners and improve the effect of space planning. 4.Neutral Landscape Model is regarded as the reference system of the real landscape that is proper, the simulation landscape produced through SIMMAP is compared with landscape indexes of the real landscape, to understand the habitat gathering situation in the study area, shortcomings is space position can’t correctly compare with, this is a restriction of SIMMAP. 5.This research examines the relation between landscape pattern and process of studying area of 2003 through percolation critical value Pc, find sources (forest land, sandy beach) no matter in which landscape indexes corresponding gathering degrees of p all below percolation critical value Pc, PD, landscape indexes, show the isolate degree of habitat patch for birds to move and population dynamic influence demonstrating critical extreme value, especially, it accord with the main characteristic that habitat patches in the real landscape is small area and high dispersed with the area. 6.It is finded in 13 landscape-types area changes during 1976-2003 that the matrix in the study is farmland over the past 26 years (rice terraces＋dry farmland); the area fluctuates greater landscape type includes rice terraces, dry farmland, the meadow, uncover ground, sandy beach, fishing pond and sink, building ground, graveyard, provincial highway, county road; The area fluctuates the less landscape type includes the forest land, River and ocean, and agricultural way.
