Guandishan Forest region is a typical mountain secondary forest region in North China. All of the original forest has been destroyed by centuries of human activities, especially the clear cutting and man made forest fire during the Japanese Occupation between 1940 and 1945. After that, the forest landscape is totally in a restoration process. Now, the forest landscape is highly heterogeneous and complicated. So it is a challenge to determine if there is any stable pattern or trend of the landscape elements...

Guandishan Forest region is a typical mountain secondary forest region in North China. All of the original forest has been destroyed by centuries of human activities, especially the clear cutting and man made forest fire during the Japanese Occupation between 1940 and 1945. After that, the forest landscape is totally in a restoration process. Now, the forest landscape is highly heterogeneous and complicated. So it is a challenge to determine if there is any stable pattern or trend of the landscape elements spatial distribution and what is the dominant affects predominating the pattern. Supported by ARC/INFO, using Spatial Trend Surface Analysis method, dynamics of distribution trends of landscape elements in the process of forest landscape restoration in Guandishan forest region is explored in this paper to grasp the general pattern of forest landscape and the dominant affects which controlling the forest restoration process. The Uniform Grid Sample Point method is used for sampling the basic data to build the trend surface model from ARC/INFO vegetation coverage of the four forest restoration stages. Three types of trend surface models are built for the four stages respectively in the paper. It includes the distribution trend of forest landscape elements along the environment gradients of (1) altitude and slope aspect, (2) altitude and slope gradient, and (3) slope aspect and slope gradient. Comparisons among the models of different stages were made carefully to reveal the general pattern of landscape element distribution and the dominant effects of the environment gradients to the landscape pattern. The results show that, in the scale of the study area, the horizontal position of the site has no obvious effect on the vegetation distribution pattern and forest restoration process. The environment gradient pattern consists of altitude, aspect and slope, and the anthropogenic disturbance regime is the dominant affects controlling the forest landscape restoration process and pattern in the study area. Forest restoration processes are different in different altitude ranges. Forest restoration process in the high altitude range (2100~2800m) in the study area basically controlled by spatial pattern of site condition with higher ecological potential, but in the low altitude range (1400~1600m) with lower ecological potential, it is controlled basically by anthropogenic disturbance regime. The effects of slope aspect and slope gradient are different in different altitude ranges. Generally, in the study area, with the decrease of altitude the intensity of slope aspect effect on the landscape pattern increases, but at lower altitude range, the changes of vegetation distribution pattern are more comprehensive because of increasing anthropogenic activity. In the altitude range of 2100~2800m, there are large differences of potential value of trend surface between different slope aspects. In the middle altitude range of 1600~2100m, the differences are small. In the low altitude range of 1400m~1600m, landscape pattern is complicated because of the comprehensive effects of slope aspect and slope gradient. In general, the smaller the slope gradient is, the smaller are the differences of vegetation in different slope aspects. The controlling effect of slope gradient is also obviously different in different altitude ranges. The controlling effect of slope gradient is the strongest at middle higher altitude range. It is not notable at high altitude range, and it is relatively lower at middle altitude range than that at middle higher altitude range. But at low altitude range, forests are distributed mostly at steep slopes because of anthropogenic disturbance regime controlled by slope gradient and slope aspect effect intensified by slope gradient. In the high altitude range of 2100~2800m, forest are mostly distributed at steeper slope with gradient greater than 15 degree in early stages, gradually the effect of slope gradient on the vegetation distribution pattern became not very obvious. In the middle high altitude range of 1900~

Based on four stages of Ariel image since 1959,and supported by ARC/INFO,the similarity index to circle (SIQ) and fractal dimension (D f) of all types of landscape patches in Guandishan forest region were analyzed in this paper.The results showed that SIQ was efficient to analyze and explore the characters and dynamics of patch shape.During the process of forest landscape restoration in the study area,SIQ of non forest patch was always higher than the forest patch.The SIQ of forest patch increases persistently in the period.The patch shape became more complex.The landscape was in the middle stage of active forest restoration and patch succession,dominated by the extension and combination process of later succession forest patch,which had more complex and diversified patch shape and more close correlation with other patches.The early succession forest patches with comparatively simple shape gradually declined.
