Advances in Studies of Indexes of Soil Quality and Evaluation

Soil quality was subjected to serious threat because of long-term man-made damage and unreasonable land using.Searching for the indexes of soil quality has recently become a research focus.The traditional physicochemical indexes can not meet the need of soil quality evaluation;Therefore,searching for the indexes which can reflect the dynamic changes and distinguish the changes of soil quality has become an important research task.In this paper,comprehensive review is made on the soil quality index and soil quality evaluation in order to provide theoretical basis for the reasonable utilization and the protection of cultivated land.
