Abstract

Lake Diatas is a tropical lake surrounded by agricultural land prone to pollution. A multivariate approach to lake water quality will be useful for lake management. The study's objectives are to describe fertiliser use by farmers around the lake, the lake's quality and trophic state spatially, and to use a multivariate approach to lake water quality. The results of a survey showed that most farmers use synthetic fertilisers because of low fertility soil, with self-estimated doses applied. The levels of total nitrogen (TN), total phosphorus (TP), and Secchi depth (SD) marginally exceeded the regulatory standard. However, the trophic status of the lake indicates an intermediate level of nutrients. Principal component analysis (PCA) showed the presence of two main factors with a variance of 85.46% – which showed the important drivers for lake water quality is mainly affected by agricultural activities around the lake. Cluster analysis showed three groups with the same water quality characteristics: the first group consists of locations with higher sulphate levels, the second with low SD, and the third with higher levels of TN and TP. Clearly, agricultural activities affect lake water quality and management regarding land use around the lake is important to prevent pollution.
农业用地周围热带湖泊水质环境的多元分析
迪亚塔斯湖是一个热带湖泊,周围是易受污染的农业用地。湖泊水质的多元方法将有助于湖泊管理。该研究的目的是描述湖泊周围农民的化肥使用情况、湖泊的质量和营养状态,并使用多元方法来评估湖泊水质。一项调查结果显示,大多数农民使用合成肥料是因为土壤肥力低,施用量自行估计。总氮(TN)、总磷(TP)和塞奇深度(SD)的水平略高于监管标准。然而,湖泊的营养状况表明营养物质处于中等水平。主成分分析(PCA)显示存在两个主要因素,方差为85.46%,这表明湖泊水质的重要驱动因素主要受湖泊周围农业活动的影响。聚类分析显示,三组具有相同的水质特征:第一组由硫酸盐水平较高的地点组成,第二组由低SD组成,第三组由TN和TP水平较高的地方组成。显然,农业活动会影响湖泊水质,湖泊周围的土地利用管理对防止污染很重要。
