吉林省黑土资源生态分类

Study on ecological classification of black soil in Jilin province

为了可持续利用黑土资源,以吉林省为例,尝试对黑土进行生态分类.综合运用主成分分析、聚类分析、模糊综合评判方法,研究了黑土生态适宜性,探讨自然、经济、社会因素影响下,不同种类黑土的生态土地类型.黑土生态分类是黑土生态区划的基础,可为黑土生态环境建设和环境管理政策的制定提供科学依据.

<Abstrcat> The black soil region in the northern China is one of the most important grain base, but after a long-term irrational utilization the quality of the black soil is degrading, in the meantime, after China's entry into the WTO, the great negative impact will be brought into the black soil region. In order to ensure the black soil a sustained use, the paper attempts to accomplish the ecological classification on the black soil regarding Jilin province as an example. Based on an analysis of ecological suitability of the black soil, different kinds of ecological land patterns about the black soil is discussed under the impact of natural, economical and social factors. The ecological classification is a base for the ecological regionalization on the black soil. It can provide scientific basis for constructing healthy ecological environments and making policies of environmental management.
