克拉玛依农业开发区水土性状与荒漠植物多样性的关系

通过分析克拉玛依农业开发区水土性状、荒漠植被演替规律和群落多样性,了解到区内植物的生长更新主要靠大气降水来维系,而土壤理化指标中的有机质、全N和全K含量增加是植物群落发展多样性的胁迫因素。与之相反,一定限度下的较高pH和粒度值,则可促进植物多样性水平的提高。分析结果还表明,土壤的全盐、全P和水分是影响植物多样性的潜在因素。

Relationship between Water-Soil Properties and Desert Plant Diversities in Agricultural Development Area of Kelamayi

By analyzing the properties of soil and water, the succession laws and the diversity of desert plant in agricultural development area of Kelamayi, it understands that growth and renewal of desert plant in this area rely on the precipitation. Some indexes of soil physical-chemical properties, the organic matter, total N, total K are stress factors that affected plant diversity. On the contrary, a certain increase of pH and grain-size is in favor of plant diversity. Additionally, total salts, total P and moisture in soil have potential impact on the plant community diversities.
