摘　　要：利用1998年和2006年两期TM遥感影像,结合森林二类调查数据,对海南省霸王岭天然林保护工程区进行景观分类和景观指数提取。通过比较和分析,结果表明,景观总体结构稳定,1998年到2006年森林面积增加了6454.2hm2。原始林破碎度降低,干扰减弱。次生林质量有所恢复,5949.86hm2的中度次生林转化为轻度次生林。橡胶林和未成林造林地大幅增加,荒地大幅减少,人工造林成效显著。但在次生林边缘地带仍然存在部分人工林侵蚀次生林的现象。Using TM remote sensing image of two periods in 1998 and 2006,as well as forestry resource survey map,this article presented the landscape classification and landscape indexes in the protected natural forest area of Bawangling,Hainan.By comparing the two remote sensing images,it showed that the landscape in Bawangling of Hainan was preserved well.From 1998 to 2006,the forest area was increased to 6 454.2 hm^2,and the virgin forest breaking was declined and the interference was weakened.Meanwhile the total interference degree of the landscape was also decreased.Although the quality of natural secondary forest recovered,it was eroded by planted forests all the same.5 949.86 hm^2 of medium secondary forest had been transformed into light secondary forest.rubber forest and young plantations were increased greatly while waste land was decreased significantly,and the result of afforestation was remarkable.
