| Abstract: |
| Pollution of livestock and poultry breeding has been one of the main factors restricting the healthy development of breeding industry in China. Integrated management of nutrient information is an effective way to ensure the healthy development of livestock and poultry breeding industry, prevent and control agricultural non point pollution, and improve the efficient utilization of resources. Decision support system (DSS) is an important means to realize integrated nutrient management of livestock and poultry wastes. This research aims to provide a strong technical support for the optimization of utilization strategy in terms of livestock and poultry breeding waste and promote the implementation of integrated nutrient management. The research proposed the disadvantages existing in the nutrient management of breeding waste in China, as well as analyzed the application developments of models and systems focusing on resource management of breeding waste at home and abroad. In addition, it introduced the basic characteristics, construction method and feasibility of DSS in the nutrient management of breeding waste were introduced. By analyzing the experience and the insufficiency existing in the DSS system at home and abroad, it put forward a method suitable for nutrient management in our country according to regional characteristics of waste disposal and utilization. Particularly, the method of establishing the database and model base as well as its effect on the overall management scheme decision was stated in detail. In view of the current situation of livestock and poultry breeding in China, it is suggested that it should improve the source and accuracy of DSS parameter database, select the index system of nutrient management of livestock and poultry wastes, construct a nutrient management model for farms, farmlands and regions, and help decision makers in livestock and poultry breeding to better realize the optimization of livestock and poultry breeding economy and resources. |
