资源简介:
通过全自动小型气象站对湖北各地区农田实时监测环境温度、环境湿度、风速、土壤含水率、本周降水量、植被指数、太阳日照时间等数据并每日上传即时数据,根据上述7个数据预测出农田土壤水分蒸发量。该预测数量可为农田水分盈亏分析提供数据支撑,指导农田科学灌溉和排水,从而提高作物的产量和质量。另外可结合地理信息系统(GIS)技术,将各地点的农田地理数据和土壤水分蒸发量信息进行深度整合和分析,绘制地理位置-土壤水分蒸发量地图,以直观的可视化形式呈现给用户,增强地理位置与土壤水分蒸发量关系的理解。每天早上通过全自动小型气象站对湖北各地区不同编号的农田实时监测,采集环境温度、环境湿度、风速、土壤含水率、本周降水量、植被指数、太阳日照时间等数据并每日上传即时数据。 通过广义回归神经网络(GRNN)方法对土壤水分蒸发量进行预测,利用主成分分析法提取影响土壤水分蒸发量的7个因子(环境温度、环境湿度、风速、土壤含水率、本周降水量、植被指数、太阳日照时间),将上述7个因子作为GRNN模型的输入量,土壤水分蒸发量作为输出量从而预测出农田土壤水分蒸发量。GRNN模型预测值与实测值拟合程度较高,模型模拟精度较高,可用于湖北各地区农田土壤水分蒸发量预测。

A fully automatic small weather station conducts real-time monitoring of farmlands with unique serial numbers in various regions of Hubei Province every morning, collecting data including ambient temperature, ambient humidity, wind speed, soil moisture content, weekly precipitation, vegetation index, and sunshine duration, and uploading real-time data daily. The farmland soil water evaporation is predicted based on these seven datasets. Such predicted data can provide data support for farmland water surplus and deficit analysis, guide scientific irrigation and drainage of farmlands, and thus improve crop yield and quality. Additionally, by integrating Geographic Information System (GIS) technology, the farmland geographic data and soil water evaporation information of each location can be deeply integrated and analyzed. A geographic location-soil water evaporation map can then be drawn, presenting the results to users in an intuitive visualization format to enhance the understanding of the relationship between geographic location and soil water evaporation. For the soil water evaporation prediction task, the Generalized Regression Neural Network (GRNN) method is adopted. Specifically, Principal Component Analysis (PCA) is used to extract the seven factors affecting soil water evaporation: ambient temperature, ambient humidity, wind speed, soil moisture content, weekly precipitation, vegetation index, and sunshine duration. These seven factors are taken as the input variables of the GRNN model, while soil water evaporation serves as the output variable, thereby realizing the prediction of farmland soil water evaporation. The predicted values from the GRNN model exhibit a high fitting degree with the measured values, and the model has high simulation accuracy, making it suitable for predicting farmland soil water evaporation in various regions of Hubei Province.
