三江平原植被景观异质性转化分析

Sanjiang Plain Vegetation Land Conversion of Heierogeneity analysis

运用马尔柯夫模型进行三江平原植被景观转化分析:可以看出三江平原植被景观异质性的增加是由于优势景观:森林、草甸、灌丛不断破碎化引起的。由于人类活动影响的加重,各种基底景观不断破碎化,斑块的形状变的更加不规则。在大量其他景观组分不断向农业用地转移的同时,农田景观组分也不断向非农业用地转移,尤其是向居民地、湿地转化。二者的输入、输出恰恰是相互关联的。

The use of Markov model to transform the landscape in the Sanjiang Plain vegetation analysis： can be seen in the Sanjiang Plain vegetation landscape heterogeneity was due to increased edge landscape： forest, meadow, shrub constantly caused fragmentation. Because of the impact of human activities increase, a variety of substrate constant landscape fragmentation, patch shape becomes more irregular. A large number of other landscape components at constant to the transfer of agricultural land, the farmland landscape components have been transferred to non-agricultural land, espe- cially to the residents, the conversion of wetlands. In fact, both the input and output are precisely interrelated.
