中文摘要 | 台灣土地的開發,長期以來以經濟為導向,著重於生產與經濟利益。由於人口成長,農業用地需求擴張,逐漸向邊際土地開發,如山坡地及海埔新生地。土地超限利用,破壞了原始林相,亦忽略環境承受能力,使得天災發生頻繁時,山坡地常成為大地反撲的據點。另外,由於全球化經濟的衝擊,台灣中南部山坡地的農業,將逐漸失去市場的競爭優勢與生存空間。一旦產業萎縮,將會釋出大量的廢棄耕地。本文研究之目的,在探討檳榔林坡地廢耕後,如何以生態工法復育及重建其環境及生態。 研究區域為嘉義縣東南方向的三層村,研究坡地位於三層村的中心處,南以陵線與白河水庫及其水源保護區為鄰,北與三層國小有一溝之隔,四周均為檳榔園。因檳榔廢耕區水土流失嚴重,初期設計以水土保持為主,並設置溪蟹、鳥類及螢火蟲觀察區。為復育鳥類,儘量保存園區內的果樹,而新植物的栽種,以漿果類樹種為主,來增加鳥類食物來源。為復育兩棲類及水生動物,在較大水池處設攔水壩,以減少枯水期的影響。在景觀方面,在步道兩側種植阿伯勒,路底之平台周圍種植油桐,山澗水道潮濕地帶種植野薑花。 研究結果發現廢棄檳榔坡地的景觀美化可帶動居民生活型態的改變,生態工法可防止小花蔓澤蘭的入侵生長及加速自然林相的形成,並營造多樣化生物的棲息空間。男一方面,水土保持的加強,確實有助於復育檳榔坡地的植被。 |
英文摘要 | The development of hillside lands becomes inevitable in the process of developing economy due to the prevalence of mountainous terrain over plain areas in Taiwan. However, under the dissemination of a new concept of environmentally sustainable development, people in Taiwan have realized that the environmental carrying capacity must be under serious consideration after the natural and man-made disasters occurred. In addition, due to the impact of economical globalization, the agriculture over the southern Taiwan has gradually lost its competitive advantage. Once the industry size is decreased, more abandoned lands will be released. This study is to investigate how to use ecological engineering methods to rebuild the environmental ecology of abandoned betel-nut hillside lands. The research land area is over the center of San-Tseng Village, which is in the southeastern part of Chiayi County. The Baihe reservoir is at the south and the San-Tseng Primary School is at the north of this betel nut garden. Since the soil erosion problem is serious, water and soil conservation is emphasized in the initial stage. Observation areas of river crabs, birds, fireflies are also established. Previous fruit trees are maintained as many as possible to attract birds. New plants, especially berry trees, are planted for increasing the food sources of birds. Blocking water facilities over large water ponds are built to restore amphibious and aquatic animals and to reduce the impact of the dry season. For the landscape design, Cassia fistula L., Vernicia fordii, Hedychium coronarium Koenig are planed beside the roads. It is found that landscape design on abandoned betel-nut hillside lands can change living style of local residents. The implementation of ecological engineering methods can prevent the invasion of Mikania micrantha Kunth, accelerate natural forest formation, and build up biological diversity. Besides, the water and soil conservation help vegetation growth over such lands. |
