landscape
To optimize the spatial structure of an ecosystem, a forest landscape was selected as a research object.
      
Based on the methods of landscape ecology and ecological planning, this paper develops a zoning project of ecosystem functions suitable for various environments.
      
Distribution of Landscape Elements Along Environmental Gradients in Over-Cut Forests
      
The method of trend surface analysis was used to analyze the distribution of landscape elements along environmental gradients in Jingouling forest farm, northeast China's Jilin Province.
      
Results showed that topographic characteristics and disturbance pattern have much more impacts on the distribution of landscape elements than do horizontal geographical position in the study area.
      
The elevation, slope aspect, and slope degree were found to be dominant features controlling landscape pattern.
      
At different altitudinal ranges, the effects of slope aspect and slope degree on the distribution of landscape elements vary markedly in orientation and intensity.
      
These differences were analyzed and discussed, and some basic rules of spatial distribution of landscape elements were proposed.
      
Long-term effect of different planting proportions on forest landscape in Great Xing'an Mountains, Northeast China after the cat
      
A landscape model (LANDIS) was used to study the long-term forest dynamics under five planting types (100% larch (P1); 70% larch and 30% Mongolian Scotch pine (Pinus sylvestris var.
      
In the evolutionary process of GA, a clustering method is provided that utilizes information from the template and the fitness landscape of the current population.
      
The vegetation pattern in the upstream of Minjiang River, and its relationship with environment factors, such as landscape position (elevation, slope, aspect), precipitation and temperature and soil are analyzed in this paper.
      
The data used in this paper were based on the landscape map derived from 1994 TM imagery.
      
Landscape pattern and eco-hydrological characteristics at the upstream of Minjiang River, China
      
The results were: (1) The selected six catchments at the upstream of Minjiang River, China were different in landscape patterns in terms of landscape type and cover.
      
(3) High correlation was detected between the landscape indexes and eco-hydrological indexes.
      
Eco-hydrological index was positively correlated with landscape contagion in contrast with the negative correlation with landscape diversity and edge density.
      
An artificial neural network model of the landscape pattern in Shanghai metropolitan region, China
      
A unimodal pattern was found only for one community (Stipa glareosa community), while at a large scale (vegetation type or landscape/region), the relationship was also found significantly positive.
      
Source-sink landscape theory and its ecological significance
