摘要

竹林廣泛分布台灣全島中低海拔區域，為台灣極重要的可再生性資源，也是過去林農賴以維生的重要林產工業原料。由於竹林大都分布於公私有林地區，但長期以來公私有林缺乏完整的例行調查，致使竹林的面積及使用情形等資訊嚴重不足。本研究利用2007年林務局委託北部公私有林調查之成果，結合國有林事業區檢訂調查及第三次森林資源調查，探討北部地區竹林資源的分布與1973、1993至2007年間的竹林資源消長變遷。研究結果顯示，2007年北部地區（包括宜蘭縣、基隆市、台北縣市、桃園縣、新竹縣與苗栗縣）竹林面積分布，以苗栗縣36,799 ha (42.24%)最多，新竹縣21,275 ha(24.42%)次之。從變遷分析結果顯示1973年竹林面積約24,482 ha，1993年61,325 ha，2007年87,127 ha。顯示北部地區竹林面積從1973年迄今，每年約增加1842 ha。分析縣市及鄉鎮層級面積的變化，結果顯示不同縣市或鄉鎮竹林面積的消長情形，其中以苗栗縣面積增加最快1973年至1993年增加約15,676 ha，每年約增加783.8 ha；1993 年至2007年增加14,474 ha，每年增加1,034 ha，足以顯示其面積增加之快速。此項結果，可供為未來竹林經營策略擬定之參考。

Bamboo forests are widely distributed in areas of low and mid elevation of Taiwan. Bamboo is one of the important forest resources that forest farmers used to depend on for living in Taiwan. Bamboo forest is mainly located in public and private forests where comprehensive routine surveys have never been conducted. Consequently, the crucial information for management of bamboo forest, such as its coverage and utilization of the resource, is still lacking. This study was to identify the distribution of bamboo forest in northern Taiwan by using the survey results from public, private forests and the national forests. In addition, with results from the Third Forest Resources and Land Use Inventory and the bamboo forest survey in 1973. Changes of bamboo forest resources among 1973, 1993 and 2007 were evaluated. This study would provide information for changes of local bamboo covering areas (at the scale of county and township), which could be used as a reference for bamboo forest management. The present study showed that the area of bamboo forest in northern Taiwan was 87,127 ha in 2007. The largest area of bamboo forest is in Miaoli County (36,799 ha) followed by 21,275 ha in Hsinchu County. In terms of the change of area, bamboo forest in northern Taiwan was 24,482 ha in 1973 and it increased to 61,325 ha in 1993. In other words, area of bamboo forest increased 1,842 ha per year. The analyses also showed the ebb and rise of bamboo covering area in different counties and townships, which could be used as a reference for the strategic decision of bamboo forest management.
