The activities of local people living in or around the nature reserves have important influences on the structure of forest communities. This study focused on the influences, which come from the firewood collecting by the local people, on the distribution of arbors. Through the investigation in 10 villages near the Wanglang nature reserve, the income levels of the villages were divided into 3 ranks using the K-means Cluster, and 3 villages, which are the closest to the average values of each rank, were chosen to do the detailed analysis. At 90 sites around these 3 villages, some information was recorded on the characteristics of arbors (species, height, diameter at breast height, and percentage of cover) and shrubbery (species, height, quantity, percentage of cover, basal diameter and weight). Based on these data, the results indicated that the cumulative quality of the timber and the tree density relative to the one of shrubby both were the function of the distance to the center of the village (independent variable). By using the SPSS (Statistical Program for Social Sciences), regressive curves estimation was made in 10 math models. From the results of estimating, significant difference could not be found among the 3 villages so that the conclusion can be made as follow: the economic gaps existing in these 3 villages didn’t affect obviously the distribution of the arbors. It is because that the economic differences lying among the 3 villages are not significant enough to cause the changing on the approaches and the quantities of firewood collection of the local people. In addition, the results of curve estimation show that the R2 reaches the peak when comparing the function between the independent variable and the cumulative quality of the timber with the Logistic Model. Simultaneously, the maximum R2 appeared when we compared the function curve composed by the independent variable and the tree density relative to the one of shrubby with the Growth Model. The distributing pattern can be easily found from the curve of the function. At first, the dependent variable ascended gently along with the increasing of the independent variable, which illustrates that if the distance to the center of the village is less than the first threshold (between 3 km to 4 km), firewood collection plays a key role in the distribution of arbors. Even if the quality and the quantity increase, the trend changes slightly. However, if the distance keeps going up, the slope of the curve rises up suddenly and sharply. The trend is caused by the dramatic intensity reducing of the negative disturbance from firewood collecting, and the existing range lies from the first threshold to the second threshold (between 7 km to 8 km). And after that, due to the human’s influence on firewood collecting reduce gradually and almost can be ignored, the increasing trend of the curve becomes gentle again, and finally, the quality and quantity of the arbors go back to what they are in the original state.
