中文摘要 | 農地是農業生產的基本要素,為不可再生之資源,除了生產作物以外更有綠化環境、保育生態及儲備能源與國家建設發展用地之機能。但由於近年來社會經濟的快速成長,農地除了傳統生產支用外,已成為未來擴大發展為生態與生活性用地的新焦點。本研究以台南縣農地為研究範圍,以農地自然生產力為基本等級,輔以選取其他相關因子的影響對基本等級作調升及調降的修正。藉此方注將農地劃分為重要農業發展區、次要農業發展區及不適農業發展區。而台南縣農地經評估,後其應保留之重要農業發展區面積約為71,513公頃,其餘農業用地,為可發展為以生活及生態為主要機能之農業用地。 |
英文摘要 | Farmland is the one of irreversible fundamental elements of agriculture. Excepting for breeding crops, it has other functions such as greening environment, conserving natural ecosystem, reserving energy resource and being an effective space for national development. Recently, because of fast economic developing and shortage of urban space, farmland have become a new focus for city and industry extending. This research used evaluating method to classify agricultural land in Taiwan and also applied GIS software as tools to build a geographic information system. We hope to provide some information for the government in the decision making of farmland use policy. We took Tainan as a research area, used the model for the classification of agricultural land importance to classification the agricultural land. This model took the natural productive of farmland as the basic index and this index was modified by other auxiliary factors. We classified the agricultural land into important agricultural development zone, sub-important agricultural development zone and non-suitable agricultural zone. The results for Tainan area were about 71,513 ha for important agricultural development zone. The rest of the farm land could be considered for the development of natural ecology and other usage. |
