Research On The Spatial Distribution Of Biomass Material Collection Points Based On Road Network Transportation Cost

The energy crisis and environmental pollution are increasingly exposed.The development and utilization of renewable energy,especially renewable biomass clean energy,will greatly solve the environmental problems caused by fossil fuels.However,the high transportation cost of biomass has always been a key factor restricting the development of biomass energy.Therefore,this article aims to reduce the cost of biomass transportation,and is committed to seeking a more reasonable spatial distribution model of biomass collection points,so that the raw material transportation cost of biomass thermal power plants built in the research area can be effectively controlled.Based on the in-depth study of energy landscape theory,this paper constructs a biomass resource potential evaluation model and a biomass transportation cost model,and takes Heilongjiang as an example to evaluate the potential of the spatial distribution of biomass resources in the region,and based on The evaluation results screen the research objects of the raw material collection point of the birth material thermal power plant,and use ArcGIS network analysis and other tools to determine the supply range and the best collection radius of the birth material raw material collection point,so as to propose a planning strategy for its spatial distribution.The analysis results show that for Shangzhi City,the 60 km actual road transportation distance is the best biomass collection range for the thermal power plant when Shangzhi City collects forest resources,crop straws,energy plants,and domestic garbage.And when the collection objects are these four types of biomass resources,the transportation cost of biomass resources is the lowest when the collection radius is set to 8km;the unreasonable spatial planning of biomass collection points will result in a significant increase in the transportation cost of biomass.When the collection objects are forest resources,crop stalks,and energy plants,the three types of biomass resources,the collection radius is set to 10 km,which saves more than 35% of the transportation cost of biomass resources;for domestic waste,the establishment of raw material collection points for biomass cannot reduce transportation costs,but has the opposite effect.At the same time,the increase in the radius of the collection point will result in a significant increase in the transportation cost of domestic waste.There are three main innovations in this research.One is to add energy plants and domestic waste on the basis of agricultural and forestry biomass to make the biomass assessment more perfect;the second is to obtain forest resources,crop stalks,energy plants and domestic waste at different levels.The transportation cost per unit distance for a single round trip on the highway;the third is to provide a research method based on ArcGIS network analysis to actually simulate the transportation situation and compare the transportation cost to get the best collection radius.This research not only provides suggestions for the collection and transportation of raw materials for existing biomass thermal power plants,but also provides reference opinions for the site selection and spatial planning of future biomass thermal power plants.
