The area changes of different forest types (km?) RE asics RETR x = Figure 2. Forest in study area in 1986(a), 2000(b), 2006(c) In summary, forest has decreased at an annual change rate of - 0.19% during 1986-2000. Closed forest was destroyed with annual loss rate of -0.5% from 2000 to 2006. The open forest decreased dramatically with annual rate of -0.7% in the same period. Shrub forest shrunk in area between 1986 and 2000 at loss rate of -0.25%. There was an increase of other forest land with annual area change rate of 0.90% (from 1986 to 2000) and 0.64% (from 2000 to 2006) respectively. The speed of deforestation from 2000 to 2006 was faster. The change rates of various forests were relatively high showing a negative state. 4.2 Forest Fragmentation Figure 3 shows the landscape metrics for forests at class level in different historical years. During the past 20 years, the numbers of forest patch increased slightly, while the average patch area decreased 96 ha. Forest decreased in the average size of patches potentially resulting from cultivation and degradation. From 1986 to 2006, the PD of forests increased from 0.059 per 100 ha to 0.062 per 100 ha. Forest land in this region affected by human activities have lower AMWPFD values (<1.30). AWMPFD of forests decreased slightly indicating that forest patch shape tended to be regular and simpler indicating more human influence during 1986-2006. The averages patch area of closed forest decreased 2737ha resulting from logging and cultivation. The MPS values of shrubs and open forest decreased while averages patch area of other forest increased probably due to the afforestation encouraged by the government. The AWMPFD of closed forest and shrub decreased by 0.002 and 0.003, respectively. It was concluded that forestland experienced the process of substantial clearing and fragmentation in the past 20 years. 2500 2000 1500 = 1000 500 at D 1986 2000 M Closed forest CJ Shrub [S Open forest 0 Other forest E Total 12000 - b 10000 - 8000 - 6000 - 4000 | 2000 a JF a. 1986 2000 2006 O Closed forest [1 Shrub 0 Open forest CJ Other forest C1 Total MPS $50 - 300 - 250 | 200 | PD 1986 2000 2006 DJ Closed forest (3 Shrub &) Open forest CJ Other forest & Total
