The objectives are to understand the pollution situation of chemical pesticides on the agricultural environment based on GIS, to comprehend the situation of agricultural planting and the basic situation of crop use, and to provide direction and guidance for pollution monitoring of ecological environment. The use of crops in various provinces and the basic conditions of pesticide use are collected and investigated, such as pesticide types, pesticide use, and effects of pesticide use. In addition, GIS technology is used to connect with the Internet and establish a monitoring system for the pollution of chemical pesticides to the ecological environment based on the basic collected information. The system analyzes the use of pesticides, as well as the areas and trends of use, and presents the results in the form of chart data, providing comprehensive and reliable information for the monitoring of pollution of ecological environment by chemical pesticides. In this process, the principles and methods of system design are strictly followed, and remote sensing image technology is used to establish a model to obtain the basic situation of agricultural landscape. Based on GIS technology, the ecological environment pollution monitoring system of chemical pesticides can effectively integrate the land planting situation, the basic situation of pesticide use, and the methods of protecting pests and diseases across the country to form a complete data system, which can present the above information in data and images to the users for the management of pollution detection. The monitoring of chemical pesticides pollution on ecological environment based on GIS can effectively and intuitively understand the situation of crop planting, the number of pesticides used, and the types of pesticides used, as well as effectively promoting the strict supervision and management of pesticide use, and the protection and development of ecological environment, which plays a major role in the stability and sustainable development of Chinese agriculture industry and can be widely used and promoted.

目的是了解基于GIS的化学农药对农业环境的污染状况，了解农业种植状况和农作物使用的基本情况，为生态环境污染监测提供指导和指导。收集并调查了各省的农作物使用情况和农药使用的基本条件，例如农药类型，农药使用和农药使用效果。此外，GIS技术还用于与Internet连接，并基于基本收集的信息建立化学农药对生态环境污染的监控系统。该系统分析农药的使用以及使用地区和趋势，并以图表数据的形式显示结果，为监测化学农药对生态环境的污染提供全面可靠的信息。在此过程中，严格遵循系统设计的原则和方法，并利用遥感影像技术建立模型，以获取农业景观的基本情况。基于GIS技术的化学农药生态环境污染监测系统可以有效整合土地种植状况，农药使用基本情况以及全国病虫害防治方法，形成一个完整的数据系统。将以上信息以数据和图像的形式提供给用户，用于污染检测的管理。
