Soil enzyme activities of limestone degraded ecosystem at its different restoration phases

Abstract

Abstract: The study showed that there was no distinct descending of enzyme activities along the soil profile of limestone degraded ecosystem,which were enhanced with progressive succession,and varied with vegetation characteristics,soil types,and soil enzyme properties.On the whole,soil enzyme activities enhanced in order of herb < Cupressuss funebris high forest<shrubbery,and under the same vegetation,limestone Cupressuss funebris high forest had higher soil enzyme activities than purple psammophytia.There was no significant correlation between soil enzyme activities and soil pH,while significant correlation was found between soil moisture content,soil total nitrogen content and soil enzyme activities,indicating that soil water and nutrient contents were the key factors of ecological restoration in this region.Different soil enzymes in the same vegetation-soil system as well as the same enzyme in the same soil type but at different restoration phases had different activities,so did for the same type vegetation but different soil type.

Key words: Limestone, Degraded ecosystem, Soil enzyme
