【摘要】：林下经济是借助林地的生态环境,利用林地资源,在林冠下开展林、农、牧等多种项目的复合经营。林下经济最大的特点是对土地多方面地、可持续性地利用,这显然是其他土地利用方式无法比拟的。在林下经济系统中,部分林业用地可提供给农业用地和家禽用地使用,除去林业用地之外其他土地也被用来造林,其作用于经济用地、薪炭林和林副产品经营的使用,有效的保护了森林资源的利用,缓解了林业工作者压力,避免了侵占或毁坏森林事件的发生。本文通过阐述广西林下经济发展动态,各个地方林下经济发展状况综述,并运用主成分分析法对以广西地区的10个地级市区林下经济发展状况为研究目标,研究各个区域的林下经济综合效益指数,并通过林下经济复合度对各个区域的林下经济发展状况评价并提出对策。结果表明：(1)总结得出,广西地区林下经济的产业模式主要有林下生态-经济-旅游模式、林-禽产业模式、林-桑产业模式、林-草产业模式、林-药模式、林-花产业模式及其他类型,发展坚持“以林为主,多种经营”方针发展林下经济,保持生态环境和谐,林业增效,农民增收,提高了林地综合效益。(2)通过主成分分析方法,筛选出27个评价指标建立广西林下经济综合效益评价体系,得出各个指标可以分为4个主成分分析,广西林下经济前4个特征值广西林下经济累计贡献率达到88.353%,广西林下经济第一产业生产总值、广西林下经济农村居民纯收入等指标,比较能体现评价体系的整体性,其权重最大,为40.12%；主成分2在广西林下经济民俗旅游总收入X9、广西林下经济民俗旅游接待人次X13、广西林下经济民族旅游从业人员X14、对当地农民使用复合经济体系具有直观影响作用,其权重是28.03%。其中柳州地区综合效益指标最高,达到了2.828。(3)广西林下经济复合度评价中,可以把广西划分为三个区域：近郊都市区、远郊平原区和生态涵养区,柳州市复合度最高,崇左市最低。并且得到,林下经济复合度对其区位位置和林区面积有很大的相关性。总结得出：以如何通过发展林下经济提高广西农林经济的实际收入以及提升该经营模式综合效益为命题,结合收集到的广西各个地区林下经济发展现状以及林业现状的实际数据为依据,加以对比分析,对规划适合广西各个地区自身发展需要的具有自己鲜明特色的林下经济作出了系统的分析并提出可持续发展策略,从而对林下经济在广西经济发展和生态地区建设中对经济、社会、环境、民生协调发展所起到的作用提出建议,为广西今后发展林业和林下经济提供参考。
[Abstract]:Understory economy is a kind of complex management of forest, agriculture, animal husbandry and other projects under the forest canopy with the help of the ecological environment of woodland and the utilization of forestland resources. The most important feature of understory economy is that land is used in many ways and sustainably, which is obviously incomparable to other land use methods. In the understory economic system, part of the forest land can be made available for agricultural and poultry use, and other lands other than forestry land are also used for afforestation, which is used for the use of economic land, fuelwood forests and forest by-products management, It effectively protects the utilization of forest resources, alleviates the pressure of forestry workers, and avoids the occurrence of encroachment or destruction of forests. In this paper, the development trend of understory economy in Guangxi and the development of understory economy in various places are summarized, and the main component analysis method is used to study the development of understory economy in 10 prefecture-level cities in Guangxi. This paper studies the comprehensive benefit index of understory economy in each region, and evaluates the understory economic development of each region through the degree of economic compounding under the forest and puts forward some countermeasures. The results show that the main industrial models of undergrowth economy in Guangxi include ecological-tourism model, forest-poultry industry model, forest-mulberry industry model, forest-grass industry model and forest-medicine model. The pattern of forest- flower industry and other types, with the policy of "forest-based, diversified management", to develop forest undergrowth economy, to maintain ecological environment harmony, to increase forestry efficiency, to increase farmers' income, and to increase the comprehensive benefit of woodland by means of principal component analysis (PCA). Twenty-seven evaluation indexes were selected to establish the comprehensive benefit evaluation system of Guangxi forest undergrowth, and each index can be divided into four principal components analysis. The first four characteristic values of Guangxi understory economy the cumulative contribution rate of Guangxi understory economy to 88.353, Guangxi understory economic primary industry gross product, Guangxi understory economic rural residents' net income and so on, can relatively reflect the integrity of the evaluation system. Its weight is the largest, Principal component 2: total income of economic folklore tourism under the forest of Guangxi X9, reception number X13 of economic folklore tourism under Guangxi forest, X14 of economic and ethnic tourism practitioners of Guangxi forest undergrowth, which has a direct impact on the use of the compound economic system by local farmers. Its weight is 28.03. The comprehensive benefit index of Liuzhou area is the highest, reaching 2.828. 3) in the evaluation of economic compounding degree under forest in Guangxi, Guangxi can be divided into three regions: the suburban metropolitan area, the far suburb plain area and the ecological conservation area, and the Liuzhou city has the highest degree of compounding. Chongzuo City is the lowest. It is also concluded that the degree of economic complexity under forest has a great correlation with its location and forest area. It is concluded that how to improve the real income of Guangxi's agriculture and forestry economy through the development of understory economy and how to promote the comprehensive benefit of the management model are the proposition. Based on the actual data collected from the understory economic development and forestry status in various regions of Guangxi, this paper makes a comparative analysis. This paper makes a systematic analysis on the planning of the understory economy with its own distinctive characteristics, which is suitable for the development needs of various regions in Guangxi, and puts forward the sustainable development strategy, so as to make a systematic analysis on the economy of the understory in Guangxi in the process of economic development and the construction of the ecological region. Suggestions on the coordinated development of society, environment and people's livelihood are provided for the future development of forestry and forest economy in Guangxi.
