Study On Optional Solutions For Fuelbreak Construction From Economic Perspectives

This study sketched out the overview of forest fires and forest fire preventionsystems construction, summarised the researches and construction situations onfuelbreaks home and abroad as well as the situations in Ningbo. Thesis studied six typicaltypes of fuelbreaks, as Myrica rubra forest, Citrus reticulate forest, Phyllostachyspraecox ‘Prevernalis’ forest, Ph. praecox forest, Camellia sinensis farm and C. Oleiferaforest,three typical mathematical models are constructed based on a comparison with thetraditional Schima superba forest. The economic benefits of these fuelbreaks in terms ofdirect economic return and input-output value are analyzed and the results showed that:The average annual direct economic benefit of each hectare of fuelbreaks aresequenced as C. reticulate forest (66212yuan/hm2)> C. sinensis farm (56400yuan/hm2)> Myrica rubra forest (42328yuan/hm2)> Ph. praecox forest (16007yuan/hm2)>Ph. praecox ‘Prevernalis’(15363yuan/hm2)> C. Oleifera forest (12013yuan/hm2)> S.superba forest (5015yuan/hm2). In terms of input-output ratio, the sequence was Myricarubra forest (1:7.11)> C. reticulate forest (1:3.29）> Ph. praecox ‘Prevernalis’(1:2.35)> C.Oleifera forest (1:2.32)>S. superba forest (1:2.26)> Ph. praecox forest（1:2.15）> C.sinensis farm (1:1.92), which was slightly different from the absolute magnitude ofeconomic benefits.In general, C. sinensis farm was high-input and high-output type, with the annualaverage economic return the second highest and the input-output ratio the lowest; Fruitforest belts were high in both input and output, with the two indexes among the firstranks, which should be prioritized in developing patterns; bamboo forest belts ranked inthe middle in the two indexes. Compared with tea farms and fruit gardens, bamboo forestbelts can be developed in an extensive way and thus could be popularized in practice.After probing into the fire prevention effects of these economic fuelbreaks, the studyconsidered it could well solved some bottlenecks by developing forest fire-resistant beltssuch as the constraints of forest land, input, forest resource protection, and thedevelopment of forest business.
