以景觀生態學觀點探討棲地模擬模型——以臺中市大坑地區為例

The Habitat Simulation Model through Landscape Ecological Approach-A Case Study on Takeng Scenic Area in Taichung City

臺中市擁有優於其他都市之公園綠地，並具有生物生存及棲息之潛力。本研究之主要目的，在於建構生物棲地模擬模型，進行生物棲地搜尋皆析，並根據實證結果，探討景觀生態環境對生物造成之影響，進而求得臺中市大坑地區適宜生物棲地之區域。本研究以赤腹松鼠（Calloscirus erythraeus）為實研究生物，根據景觀生態學原理，應用AutoCad與GIS軟體建構生物棲地模擬模型。模擬包括領圈模式模擬及生物地模式模擬，前者可推論模擬模型之可行性，後者可觀察實證生物與景觀生態環境之間的關連。由生物棲地適宜分析區位選定之分析 ，可推論在大坑地區具有赤腹松鼠較佳生存優勢之區域，包括：1.東南部闊葉林區。2.山坡地中北部區域。3.山坡地西南部邊綠闊葉林環境。4.北部闊葉林區。5.中部零星闊葉林及各類型作物區。6.山坡地西部零星闊葉林及各陽型作物區。

Taichung City, which provides habitats for livings, has better parks and grasslands than the other cities in Taiwan. the purposes of the study are establishing a simulation model for biological habitats to examine the influences of landscape environment on biology, and to look for the suitable distribution for biological habitats at Takeng scenic Area in Taichung city. The study species of the study is Calloscirus erythraeus. The simulation model, is established based on the landscape ecological principle by applying AutoCAD and GIS. The simulation comprises in two parts: model for territory simulation and model for biological habitats simulation. The first one can analogize the feasibility of the simulation model, and the other can examine the coloration between the species and landscape ecological environment. According to the analyses to the distribution suitability of biological habitats, we conclude that the better living areas for Calloscirus erythraeus in Takeng scenic Area are as follows: 1.broad-leaved tree areas in the south-east; 2.north-middle areas of hillsides; 3.broad-leaved tree areas in the south-west of hillsides; 4.broad-leaved tree areas in the north areas; 5.fragmentary broad-leaved tree areas and other crop fields in the middle of the area; 6.fragmentary broad-leaved tree areas in the west of hillsides.
