" School of Urban and Environmental Sciences, Northeast Normal University, 130024 Changchun, China - joycehf@126.com ® School of Computer Science and Information Technology, Northeast Normal University, Changchun 130117, China — lovercrane@hotmail.com Commission VIII, WG VIII/8 KEY WORDS: Land cover, trajectory analysis, Forest, Landsat, GIS, Changbai Mountains, ABSTRACT: Based on the information from integrated Landsat TM/ETM images and geographic information systems (GIS), using dynamic model, landscape indices and temporal trajectory analysis, spatio-temporal changes in forest in the northern area of Changbai Mountains were investigated in the past 20 years. The results showed that the forests decreased by 141461 ha at the annual decrease rate of 0.19% from 1986 to 2006. The numbers of forest patch increased, while the patch size of forest land declined. Forestland experienced the process of substantial fragmentation. Close forest showed a net reduction of 13.3x10*ha. The typical trajectories of forest changes included forestland-forestland-cropland, forestland-cropland-cropland, forestland-forestland-grassland and forestland- cropland-built-up land. The total area of human-induced change is 1.7 times than that of natural change in the study area. Population, cropland area and gross domestic product increased significantly as forests decreased. 1. INTRODUCTION Forest plays a critical role in the global terrestrial ecosystems. With the economic development and population growth, forest ecosystems are being rapidly degraded or endangered in many regions of the world (Li et al. 2009). Forest fragmentation due to land use is a major reason for the declining biodiversity in forest ecosystems and considered to be a primary threat to terrestrial biodiversity (Harris 1984; Armsworth et al. 2004; Pichancourt et al. 2006; Cakir et al. 2008). Quantitative and spatial forest change information is critical for addressing many pressing issues including global climate change, carbon budgets and sustainability. Changbai Mountain, the highest mountain in the east of the Eurasian Continent, is covered with a wide range of distinct altitudinal vegetation types featuring the Earth’s richest biodiversity in the cool temperate zone (Tang et al. 2011). Coupling with natural disturbance (e.g. fire, insects), substantial losses of the old-growth forests and fragmentation in forest landscapes of Northeast China has been found during the last decades, driven from human activities, especially forest clear- cutting, logging and agricultural encroachment. Most of the mixed broadleaf/Korean pine (Pinus koraiensis) forests have been replaced (plantation-style) by faster-growing species such as larch (Larix sp.), poplar (Populus sp.) and birch (Betula sp.) (Jiang et al. 1999; Xiao et al. 2002). Till now, most of the efforts have been focused on the forest landscape change in Changbai Mountain Nature Reserve and its surrounding areas or in the forested areas under the jurisdiction of forestry enterprises (Zheng et al. 1997; Zhao et al. 2001; Chang et al. 2003, 2004; Yu et al. 2004; Hao et al. 2004; Liu et al. 2005a; Wang et al. 2009; Deng et al. 2010; Huang and Jiang 2010; Tang et al. 2010; Dai et al. 2010). The objectives of this study * Corresponding author. were to quantify the spatio-temporal pattern of forests, and to characterize the forests fragmentation process and forest change trajectories of Yanbian Korean Autonomous Prefecture in the northern foot of the Changbai Mountains during 1986-2006. 2. STUDY AREA The study area is located in 41?59'-44?30' N, 127?27'-131?18' E, which covers an area of 4.3x10*km°, accounting for a quarter of the total area of Jilin Province. It borders Russia in the east and faces Democratic People's Republic of Korea across the Tumen River in the south. Bearing a temperate humid monsoon climate, the study area is characterized by four clear seasons. Annual mean temperature in this area is between 2 and 6°C, and annual average precipitation ranges from 400 to 650 mm. The sunshine duration is 2300-2800 hours, and no ground frost exists for 50- 100 days. The annual average wind velocity is 2-4 m/s. Here the broadleaved/Korean pine (Pinus koraiensis) forest dominates. The main soil types include grey-brown forest soil, white starched soil and meadow soil. Since the 1950s, large- scale clear cutting and selective cutting have been made in this area, which resulted in gradual degradation of the forest ecosystem (Zhang et al. 1999). Historically, the prefecture consisted mainly of remote agricultural communities engaged in small scale farming, especially rice farming. Agriculture has been a very important pillar of the local economy throughout the study area for a long period. 3. METHODS
