以2004年和2009年两期的八达岭林场林相图以及森林资源二类调查数据为基础,在Arcgis9.3软件平台上进行空间信息建立和处理,利用景观格局指数和转移矩阵法分析了八达岭林场森林景观格局的动态变化,并利用马尔可夫模型对未来10年(至2019年)森林景观类型动态变化趋势进行了定量预测,为八达岭林场森林景观规划提供基本依据。结果表明:八达岭林场森林景观类型变化的主要特征为阔叶林面积总量减少,针叶林和混交林面积总量增加,疏林地类型消失;景观破碎化程度有所改善,各景观类型趋向于更加均匀合理的方向发展;预计至2019年八达岭林场灌木林仍然占主导地位,阔叶林会继续减少。
以2004年和2009年兩期的八達嶺林場林相圖以及森林資源二類調查數據為基礎,在Arcgis9.3軟件平檯上進行空間信息建立和處理,利用景觀格跼指數和轉移矩陣法分析瞭八達嶺林場森林景觀格跼的動態變化,併利用馬爾可伕模型對未來10年(至2019年)森林景觀類型動態變化趨勢進行瞭定量預測,為八達嶺林場森林景觀規劃提供基本依據。結果錶明:八達嶺林場森林景觀類型變化的主要特徵為闊葉林麵積總量減少,針葉林和混交林麵積總量增加,疏林地類型消失;景觀破碎化程度有所改善,各景觀類型趨嚮于更加均勻閤理的方嚮髮展;預計至2019年八達嶺林場灌木林仍然佔主導地位,闊葉林會繼續減少。

Based on the data of forest resource management survey in Badaling forest farm in the period from 2004 and 2009,the forest landscape pattern map was obtained on the platform of Arcgis 9.3 which was used as the spatial information processing tool .The dynamic analysis of forest landscape pattern in Badaling for-est farm was conducted by the landscape pattern index and transfer matrix method .The Markov model was used to predict the trends of forest landscape types in the subsequent ten years .It provided the fundamental basis for the landscape planning of Badaling forest farm .The result indicated that the primary characteristics of forest landscape types were as follows:the areas of coniferous forest and mixed forest increased ,the area of broad-leaved forest decreased ,the open forest land disappeared , fragmentation degree of forest landscape improved , and the evenness of the landscape types showed a rational trend .It is predicted that the total areas of shrub wood will still be the main type and the area of broad-leaved forest will decrease by 2019.
