普光气田生态监测及发展趋势分析

Ecological Monitoring and Analysis of Development Trend in Puguang Gasfield

对普光气田周边区域典型植物和农作物叶片、农作物籽粒及土壤进行监测,同时进行生物多样性调查。与2016年监测结果相比较,2017年典型植物和农作物叶片pH值、叶绿素含量略有升高态势,含硫量呈下降趋势;农作物籽粒淀粉、蛋白质、脂肪含量呈下降趋势;区域内土壤pH值、有效硫、有机质呈上升趋势,表明气田开发和净化厂运营没有对当地生态环境产生不利影响。

Leaves,grains and soil of typical plants and crops around Puguang gas field are monitored,and the biodiversity is also investigated.Compared with the monitoring results in 2016,in 2017,the pH value and chlorophyll content of the leaves of typical plants and crops increase slightly,while the sulfur content has a decreasing trend.In addition,the contents of starch,protein and fat in grains of crops show a decreasing trend.Moreover,the soil pH value,available sulfur and organic matter in the region have an upward trend.These indicate that the development of gas field and operation of purification plant have no adverse impact on local ecological environment.
