研究退化湿地的植被演替过程中土壤物理化学和微生物大小、活性和微生物群落结构的变化以及植物物种变化和地上生物量变化与土壤养分和微生物大小、活性和微生物群落结构之间的关系
本项目的执行,将有助于深入理解人类活动影响下的湿地退化的植被演替及其对微生物群落结构和微生物大小以及活性的影响,对三江平原退化湿地的恢复和自然湿地保护等具有一定的理论和实践意义。
针对三江平原大规模的湿地开垦和水稻种植等引起的湿地退化,而且湿地土壤利用方式和植被覆盖对其本身生态环境有重要的影响,本项目拟通过改善土壤物理化学和微生物大小、活性和微生物群落结构有利于湿地的持续性利用和退化湿地的恢复,从恢复三江平原退化湿地生态环境的角度出发,将典型沼泽湿地、沼泽化草甸、湿地岛状林和湿地垦殖旱田中原生植被作为对照,研究退化湿地的植被演替过程中土壤物理化学和微生物大小、活性和微生物群落结构的变化以及植物物种变化和地上生物量变化与土壤养分和微生物大小、活性和微生物群落结构之间的关系。本项目的执行,将有助于深入理解人类活动影响下的湿地退化的植被演替及其对微生物群落结构和微生物大小以及活性的影响,对三江平原退化湿地的恢复和自然湿地保护等具有一定的理论和实践意义。 展开

Wetland vegetation succession of research degradation in the process of soil physical and chemical and microbiological size, activity and the change of the structure of the microbial community and plant species change and the ground biomass change and soil nutrient and microbial size, activity and the relationship between the microbial community structure
This project execution, and will help to the further understanding of human activities under the influence of the vegetation of the wetland degradation and microbial community succession of microbial structure and size and the influence of the activity, the degradation of the sanjiang plain wetland restoration and natural wetland protection has certain theoretical and practical significance.
The scale of the wetlands in the sanjiang plain reclamation and caused the rice planting the wetland degradation, and wetland soil USES and vegetation coverage of the ecological environment itself has an important influence, this project is through the improvement of soil physical and chemical and microbiological size, activity and microbial community structure of benefit to the wetland's sustainable use and degradation of wetland restoration, from the restoring degraded wetland sanjiang plain environment Angle, will swamp wetland, the typical swamp meadows, wetlands, forest and overexploitation of wetland island in the two primary vegetation as a comparison, the degradation of the wetland vegetation succession process of soil physical and chemical and microbiological size, activity and the change of the structure of the microbial community and plant species change and the ground biomass change and soil nutrient and microbial size, activity and the relationship between the microbial community structure. This project execution, and will help to the further understanding of human activities under the influence of the vegetation of the wetland degradation and microbial community succession of microbial structure and size and the influence of the activity, the degradation of the sanjiang plain wetland restoration and natural wetland protection has certain theoretical and practical significance.
