Abstract:

It is helpful for scientifically drawing up the energy policy and reasonably guiding the rural household development to study the impacts of the regional geographical features on the energy consumption. Taking Linwei District, Shaanxi Province as a case, the responses on the rural household energy use to the regional geographical features in the lower reaches of the Weihe River are studied by questionnaire survey face to face, remote sensing image, GIS technology, and contribution rate method. The conclusions are as follows. Firstly, the rural household energy use in different regions is depended on the regional geographical features. In the plain the more fossil energy is used because of the convenient transportation conditions, in the loess tableland the clean energy biogas is utilized more as a result of the advanced and developed farm industry, while in the hill the firewood is the absolutely dominant energy type on account of the rich forest resources. Secondly, the response of each kind of energy to the geographical features is different. Straw is dramatically impacted by the factors of the road cover and terrain, while it is irrelevant to the cultivated land. Firewood consumption is influenced obviously by the factors of the terrain, construction land and cultivated land. Coal consumption is closely related to the road cover, construction land and cultivated land, while it is restricted in the hilly and wooded regions. Biogas is possibly popular to be used in the regions which possess more cultivated land or larger population, while it is restrained in the regions where there is convenient transportation or hilly land. Solar energy consumption is obviously advantageous in the regions which have more cultivated or construction land. On the contrary, it is disadvantageous to be utilized in the regions, where there is higher altitude or more forest land. Honeycomb briquette and electricity on the whole belong to the common energy types and are utilized here and there in the study area, so they are not influenced obviously by the geographical features. Thirdly, the functional zoning of the dominant energy type is instructive to work out the policy of rural energy use. The firewood is more possible to be used in the hill while the biogas and coal are easier to be adopted in the plain or the loess tableland. The coal or firewood is possible to be displaced partly by the electricity, liquefied petroleum gas or natural gas in the plain, where its transportation is convenient and the economy development level is high. Finally, the paper points to that the rural household energy use is comprehensively affected by many factors, but the factors of the geographical features are primary and essential, especially to the different types of regions. Of course, change of the land use or transportation condition will result in the adjustment of regional energy use structure.
