Status and forecast of landscape in Dagan FLR demonstration area
gradually from 42. 06ha in 2009 to 3. 64ha in 2089, the occupation rate (area
ratio) would reduce by 9. 62 % while secondary forest degraded forest land
and plantation would increase slightly that would result in landscape heterog<strong>en</strong>eity
decrease and the landscape would reach a relatively steady state by the
year 2089. Occupation rates of degraded primary forest, secondary forest, degraded
forest land, plantation and non-paddy field would be 0.91 % ,
16. 75% , 5. 15% , 65.98% , and 2. 84% respectively at steady state. Overall
structure of landscape would not change fundam<strong>en</strong>tally, and plantation
would be the matrix and other types would mosaic, but quality and production
pot<strong>en</strong>tial of the landscape would be significantly reduced. Degrade primary
forest would be developed into plantation by human disturbances driv<strong>en</strong> by e­
conomic interest and traditional slash and bum farming. Degraded primary
forest are mainly distributed in hill peaks with higher elevation, playing an extremely
important ecological function, is the main body for ecological <strong>en</strong>vironm<strong>en</strong>t
construction. The loss of degraded primary forest would bring some <strong>en</strong>vironm<strong>en</strong>t
problems, such as biodiversity loss, soil erosion and thereby cause
social and economic problems such as deterioration in the quality of forest
products, <strong>en</strong>ergy shortages, and income decrease, etc. Overall, this landscape
dynamics would not be consist<strong>en</strong>t with socio-economic developm<strong>en</strong>t of
the demonstration area, especially the sharp reduce of degraded primary forest.
Therefore, appropriate interv<strong>en</strong>tion should be undertak<strong>en</strong> on curr<strong>en</strong>t landscape
pattern to improve the positive direction of land use.
