Abstract: Taking the ecological reconstruction site conditions and plant growth monitoring as the study example,and combing with the actual situation in Yanshan mining wasteland,the sensor technology and automatic control technology are used to the rock slope vegetation restoration filed,a water harvesting system is designed.According to the water requirements of different plants in different growth stages,the irrigation of plants is conducted,so as to meet the requirements of plant growth and improve the plant growth rate.The GPRS wireless transmission module is used to transfer the real-time measurement data to the man-machine interface,so as to facilitate system testing and parameter setting and improve the monitoring technical level of ecological reconstruction of rock slope.

Key words: Rock slope, Automatic irrigation, Temperature and humidity sensor, GPRS
