Relationship Between Forest Landscape Patterns and Environmental Factors in Liaoheyuan Nature Reserve of North Hebei Province
Based on the data from the second class investigation of forest resources in the Liaoheyuan River Natural Reserve
grid quadrats sampling and CCA(canonical correspondence analysis) were used to analyze the relationship between the spatial distribution of forest landscapes in the Liaohe yuan River Natural Reserve and its environmental factors. (1) Overall performance of the forest landscapes is that the plantations are located in low-lying areas and natural forests
in high altitudes
which is the same as the distribution of the CCA ordination diagram. Monte Carlo test results show that elevation and slope are the main environmental factors affecting the differentiation of forest landscape patterns. (2) In the Natural Reserve
aspect
canopy density and soil thickness have very limited influence on the spatial distribution of forest landscape elements
and elevation is found to be the main factor to control the spatial distribution of forest landscape elements
followed by slope. Both indirectly control water
hot conditions affecting the distribution of stand species
