Energy Flow Analysis And Logistics Network Design Of Crop Biomass Energy In Heilongjiang Province

Biomass energy is a renewable clean energy, reduction in energy reserves, rising prices, growing pressure on the environment of today, development and utilization of new energy has become a problem of common concern in the world. Biomass energy because of its environment-friendly and economic practicality, so that its research and application of government and scientists attention. Therefore, it is of important theoretical and practical significance to study the reasonable evaluation of plant biomass and form the industrial chain of renewable resources. In this paper, the use of biomass energy evaluation of emergy analysis, by the center of gravity method, analytic hierarchy process and linear programming model that annual raw materials transportation plan to achieve minimum cost and time consuming the shortest economic goals. Concrete results are as follows: 1. To Jiansanjiang Nongken administration as the study area, on main crops(corn, rice and soybean) planting system and straw production system emergy analysis, to construct the index system, provide a theoretical basis for plant biomass energy reserves of quantitative analysis. 2. Design and optimize the biomass feedstock logistics network, the first step is to calculate biomass feedstock logistics cost analysis, secondly based on gravity method for purchasing and storage location and application level analysis method was used to optimize the alternative storage, production plant and storage location model; 3. Using linear programming model of raw materials to the logistics network of calculation and analysis, come to the annual raw material delivery plan, and with the vehicle equipment and working time to planning, achieve the minimum cost and time consuming the shortest economic goals.The emergy analysis, various different forms of energy and material are unified to the same index system of evaluation, and combined with the life cycle method, evaluation of the natural environment resources in plant growth and processing, application and disposal of the a series of life form conversion process in tribute offered the resources and the environment of investment and economic put comparison possible, evaluation system of innovation. Based on Arc GIS, the optimal route of biomass logistics network is optimized, and the economic target of the lowest cost is the innovation of the method.
