Soil biochemical factors

The present study tries to determine the seasonal variation pattern of soil microorganisms, soil biological activity, soil enzyme activity and temperature, rainfall, soil nutrient status in a Eucalyptus ABL12 plantation with different undergrowth, located in Danzhou, western Hainan Province, and the potential allelochemicals in the related soil.

本研究以剛果12號桉(Eucalyptus ABL12)人工林土壤為研究對象,對土壤微生物、土壤生物化學活性、土壤酶活性以及氣溫、水分、土壤養分的季節變化動態進行測定,對土壤中的潛在化感物質進行分離鑒定,目的在于全面系統地了解桉樹人工林土壤微生物與相關生態和環境因子之間的關系,以便為改善桉樹人工林生態系統的生態環境,保持林地土地資源的可持續利用,以及桉樹人工林持續經營提供理論依據。

To effectively control heavy metal pollution of city roadways induced by motors, the pollution index method was adopted to analyze and evaluate the characteristics of heavy metal pollution of roadway dust and topsoil near by roadside trees, and grasp the status of heavy metal pollution of city roadways.

為了減輕汽車行駛導致的城市道路重金屬污染,采用污染指數法分析、評價東京城市道路粉塵、行道樹表層土壤的重金屬污染特征,掌握道路受重金屬污染的狀況,探討行道樹樹葉對重金屬的捕獲能力及樹種間的差異。

The ratio of the content of an element in topsoils (depth 10-20 cm) to its content in deep soils (depth 150-200 cm) is called artificial environmental concentration coefficient in soils.

南京周邊地區開展多目標地球化學調查獲取了“雙層土壤”各元素的含量,表層土壤的元素含量與其深層土壤元素含量之比值即稱之為土壤中該元素的人為活動環境富集系數(簡稱環境富集系數),筆者介紹了有關環境富集系數的計算方法。
