摘要
以崇州国营林场干沟工区1987年二调资料和2004年实测数据为基础,在ARC/INFO支持下,应用地理信息系统(G IS)技术,通过马尔柯夫转移矩阵模拟该地区的景观变化过程。结果表明:该区的两级分类景观类型格局变化均无明显差异(p=0.05),可用该模型模拟景观未来的变化情况:该工区天保工程实施后林分更新和经营活动已由单一的经济效益向多树种、林分综合效益和利用自然更新方向发展,对提高林分的综合效益和服务功能有积极的作用。
Based on the data of Class 1I investigation in 1987 and actual survey in 2004,the dynamic changes of forest landscape were analyzed by using GIS technology and ARC/INFO support through Markov model. The results indicated that there was no significant difference （p = 0. 05 ） between forecast values and actual values of landscape patterns. It was possible to simulate the future landscape pattern of this region. These results also showed that more attention should be paid to multiple species, integrative benefits and using natural regeneration from economic benefit for forest regeneration and managemeni after the project of natural forest resource protction being carried out at this site, thus having a positive effect on promoting synthetic benefit and service function of forest.
