Abstract
Along with the rapid development in populous Taiwan, the urban-countryside space gradually becomes a continuum. A disordered, fragmented landscape derived from the expansion of uncontrolled urban development, inevitably caused a profound impact on countryside environment, including its productive and leisure functions. Landscape is a high-value nonrenewable resource, defined as an area with special aesthetic, ecological and cultural character. Therefore, landscape protection should be base on analyzing the natural environment, ecological process and human activities. Countryside landscape planning should fit into the national landuse planning hierarchy. This study focus on delineation of regional landscape protection, and adopts the landscape-led method: “ Landscape Character Assessment” to classify and describe landscape character; supported by calculating landscape metrics.
Results show that the whole study area can be classified into 10 landscape units through a top-down “ land character type – visual unit” framework, and integrate other information like image element, to complete the description of each unit. According to the landscape character description, there are two criteria – maintaining landscape naturalness and increasing landscape diversity – which can be used to select suitable set of metrics to be calculated. These metrics are the bases to analyze different landscape cover types and its spatial signature.
Finally, based on the results from landscape characterization and quantitative analysis, each unit was assigned a statement for its whole zone and intra zone landscape management. Whole-zone planning takes such strategies like protection / maintenance / enhancement to achieve landscape naturalness and landscape diversity. Intra-zone planning composed of 6 “landscape dominant items”. That is to display the rich character rooted in each unit, and to form a natural and diverse landscape. This study can also be linked upward to national landscape planning and downward to local constructive program.
