| 摘 要： | 基于克拉玛依减排林区的土壤和地下水取样分析结果,应用生态系统服务价值的原理与方法,分析了克拉玛依减排林区的土地开发效应.结果表明土地开发已取得一定的正效应:已开发用地土壤有机质、有效N和速效K的质量分数均高于未开发用地,土地开发明显地改善了土壤的养分状况;土壤浅层总盐量降低67.5%,土壤盐渍化现象得到有效控制;林地生态系统服务价值高达1.5417×109元/a.同时,土地开发也产生了一些负效应:地下水pH值、电导率、矿化度和全盐量均高于未开发用地,减排林区地下水化学特征不利于区域减排林效应的持续发挥;土壤有效P质量分数偏低,也不利于林区植被的生长.

| Abstract: | The effects of land development in Karamay artificial forest of carbon dioxide capture were analyzed based on the analytical results of soil and groundwater samples,coupling the theory of ecosystem services value.The results show that certain positive effects have been obtained through the land development.The mass fractions of organic matter,available nitrogen and fast-acting potassium in soil are all higher in the developed land than in the undeveloped.The condition of soil nutrient in the forest has been improved obviously.The mass fraction of total salt in soil is reduced by 67.5% in the developed land.The phenomenon of soil salinization has been controlled well.The forest ecosystem services value is 1.5417×109 RMB¥·a-1.However,there are also some negative effects along with the positive ones.The condition of salt in groundwater has deteriorated.The value of pH,conductivity,salinity and total salt are all higher in the developed land than in the undeveloped land,thus the chemical features of ground water is not sustainable for the CO2 capture effects of the forest.The available phosphorus is becoming lower in mass fraction,which can not satisfy the development of forest plantations. |
