本文關注於國立臺灣大學生物資源暨農學院實驗林管理處(以下簡稱林管處)及其轄內之契約林農(以下簡稱林農)於契約林地違約從事農業使用認知之差異。經查林管處本於契約林地管理者職權，擬處罰林地違約農用之林農或收回違規農用之承租地，惟部分違約林農卻認為渠等林地農用之方式，條順應當地自然生物資源特性，並未破壞林地健康，況且長年來孕育的人地情閣，早已形成尊重自然的生產栽種模式。因林管處和林農對於林地利用有不同思維，這引發衝突。
愛此，本文透過深度訪談和問卷調查法，以瞭解林管處與林農對於契約林地 使用之意見，並以Walck 和Strong (2001) 建立的權力關條架構為基礎，分析林 管處與林農因利用契約林地而產生權力互動倩形，釐清違規使用的問題癥結，並 獲致以下結論: (1)造林契約僵1c無法妥善管理契約林地; (2) 契約林地林用收 入無法滿足林農生計之需; (3) 林農之保育概念難以形成契約林地保育之共識。 最後，本文針對上述課題，提供涵蓋永續發展環境、經濟與社會三面肉之具體解 決對策: (1)儘速調整契約規範'從現有主僱關條轉變為合作關條; (2) 考量林 農生計需求，兼採需求層次概念保育利用契約林地; (3) 凝聚社群力量，建立當 地林農組織保育契約林地。

This study investigates the dispute between the Experimental Forest of National Taiwan University (abbreviated as NTUEF) and its contracted forest-farmers about the legality of the farmers5 agricultural use of their leased forestlands. The NTUEF intends to fine or evict the forest-farmers when their agricultural activities in the leased forestlands are treated as a breach of contract. Conversely, some of the farmers accused of breaching their contract regard their agricultural uses as conforming to the requirements of local bio-resources, and thus do not detriment the development of the forestry. Additionally, the famers contend that they have lived there for such a long time that they have grown to love and respect the local natural environment, and have therefore adopted an eco-friendly production model. Different interpretations between the two parties concerning how to use the forestland leads to conflicts. This study analyzes the opinions on both sides of the debate using in-depth interviews and questionnaires. The collected data are further analyzed based on Walck and strong-(2001) Structure of* Power Relations to clarify the power relationship between NTUEF and the forest-farmers on illegal forestland use. The analysis leads the researcher to the following conclusions.
1. The inflexibility of* present forest cultivation contracts makes them inadequate for encouraging proper management of* the forestland 2. Forest farmers cannot survive only on the money received from planting trees. 3. Fores'fanners have divergent views on conservation, and cannot reach a consensus on the general conservational picture.
Based on these fmding-this study proposes three solutions covering environmental sustainability, economics and society.
1. Redraft the regulations in the current contract, chan^in^the landlord/tenant relationship to a co-operative on- 2. Adopt a hierarchy of* needs to preserve the forestlands, while considering the livelihoodsofrorestfarmer- 3. Form an organization to gather the local forest fanners as a whole community to conserve the forest.
