Research On Dynamic Monitoring And Management System Of Agroforestry Operating Environment

The agroforestry operation is an innovative industrial structure model that integrates forests and crops on a basis of taking into account the ecological environment,the forest management and the growth of forests and crops.Such model plays a favorable effect on the following aspects,namely,local microclimatic factor,soil and water conservation,soil fertility,biodiversity and dust fall,as well as regulation of carbon dioxide and oxygen in the air,etc.,which can effectively solve soil erosion,land desertification and is considered as an important strategy to realize both benefits of ecology and economy.Besides,it also has great significance to solve social contradictions.In this paper,the dynamic monitoring and management system of agroforestry operating environment is studied and developed,and the purpose is to monitor the growth environment of forests and crops,understand the environmental changes of agroforestry operating system through real-time supervision and processing.Its ultimately target is to lower the management cost of forests and crops,reduce manual intervention,improve the level of productive forces and provide environmental monitoring for the agroforestry operation.The main work of this paper is as follows:(1)In Dongting Lake bottomland,four types of agroforestry operating systems is taken as the study objects,namely,the poplar plantation-leaf mustard,poplar plantation-tuber mustard,poplar plantation-pumpkin and poplar plantation-white gourd.Yuanjiang Nanzui Cyprinoid Pond that located at South Dongting Lake bottomland and the industry-university-research base of Huarong Innovation Agriculture and Forestry Science and Technology Co.,Ltd that located at East Dongting Lake bottomland are considered as the study regions to conduct experiment design and sample survey;besides,installation of relevant hardware and software equipment for environmental monitoring of agroforestry operating system is also determined.(2)By analyzing the agroforestry operating system of poplar plantation and its environment,seven indexes of light intensity,temperature,air,soil fertilizer and porosity,water content,forest selection and disease insects that have the greatest impacts on the operating system are chosen as the dynamic monitoring factors of plant growth.Meanwhile,the forest density in the operating system of poplar plantation is selected as the monitoring index of management,in order to study the environmental dynamic monitoring system.(3)An environmental dynamic monitoring and management system of agroforestry operation that based on B/S structure is researched and developed through real-time monitoring.It can monitor the changes of current environment in real time and propose corresponding strategies according to the monitoring situation.(4)Based on the analysis of the environmental monitoring indexes of agroforestry operating system,the effects of poplar pure forest,poplar-melon,poplar-pumpkin,poplar-leaf mustard and poplar-tuber mustard on soil environment are studied,respectively;in addition,their economic effects on different agroforestry operating models are compared and analyzed.The monitoring and management system of agroforestry operating environment is simple and interactive,which can monitor the environmental indexes,such as light intensity,temperature,air,soil fertilizer and porosity,moisture content and insect pests dynamically.Moreover,this system can automatically analyze the forest density,and possesses with the function of indicating selective cutting.Therefore,it is able to provide to provide information management platform and technical support for the agroforestry operation.
