Dynamics analysis on landscape patterns of Chinese tropical and subtropical plantation areas
摘要
Abstract
Forest subcompartment data for the survey years of 1998, 2004 and 2009 were used to systematically analyze the dynamics of landscape spatial structure at Experimental Centre of Tropical Forestry of Chinese Academy of Forestry, in terms of landscape index by using Geographic Information Systems (GIS). It is found that the area of forest landscape element accounted for over 49% of all landscape elements area from 1998 to 2009 and showed the characteristics such as large area, many patches and high dominance index, which played a leading role in the landscape structure and function of Experimental Centre of Tropical Forestry. The afforestation for undeveloped forests, non-forests and no stumpage forests were reduced by 283.83, 538.84, 1 507.11 hm2 during 1998 - 2009, respectively, while the open forest land area disappeared in 2004 and 2009. However, forestation-suitable land area was growing, and nursery and auxiliary production area which were used to serve the business afforestation displayed a slight rise. These changes were related to the strengthening of the forest cultivation, the fine forest management and the adjustment of forest land-use patterns. [Ch, 3 tab. 26 ref.]关键词
