Land Use Regionalization in Poor Counties in Mountainous Areas Based on Targeted Poverty Alleviation

Land use regionalization is a strategic measure for the rational use,management and protection of land resources based on local conditions.Based on the needs of targeted poverty alleviation and rural revitalization strategy and the analysis on the natural and socioeconomic conditions,characteristics of land resources,and the current status of land use in Luquan County,corresponding regionalization indices were selected from four aspects:economic environment conditions,socioeconomic conditions,land resources and land use structure,and poverty alleviation and development level,a scientific and feasible index system for land use regionalization was constructed,and land use in Luquan County was regionalized by using systematic cluster analysis method.The results show that the 16 townships(towns)of Luquan County were divided into four land use regions,poverty alleviation region for development of new town and characteristic industries in the southwest(I),agricultural development and ecological poverty alleviation region in central mountainous area(II),poverty alleviation region for development of characteristic agriculture and tourism towns in eastern plateau mountainous area(III),and poverty alleviation region for development of characteristic industries and protection of land economy in the northern alpine valley area(IV).In addition,suggestions were put forward for the rational use of land in each region.

旅游资源非优区的园区化建设探讨——以吕梁山苍儿会旅游经济园区为例

旅游资源非优区主要是在资源质量及其开发条件等方面表现出“非优性”的特征。在区域发展中如果仍然沿用传统的旅游资源开发思路和方法,必然使区域旅游业处于市场竞争中的劣势。因此,对于该类型区域有必要探索出新的经济发展思路。从区域比较优势角度,旅游资源非优区的发展应以资源禀赋特征为基础,以旅游经济园区发展为主体,走产业多样化的道路。以吕梁山苍儿会生态旅游经济区为例,提出加快园区化建设的步伐,促进旅游经济与区域产业经济的良性互动,是避免片面强调旅游经济而抑制其它产业发展,以及促进区域可持续发展的根本战略选择。

基于遥感信息的吕梁山贫困区生态安全评价

本文基于四个时段的遥感影像光谱信息计算了吕梁山连片贫困区的遥感生态指数(RSEI)及植被覆盖度(FVC),分析了其生态环境时空变化规律.结果表明:(1)1993~2018年间研究区FVC整体呈下降趋势,FVC由1993年0.65下降到2018年0.55;而RSEI整体上亦呈下降趋势,由1993年的0.47下降到2018年的0.40.(2)研究区整体生态环境呈退化趋势,其中北部、南部退化最为严重,除黄河沿岸外,其他河道沿线区域的FVC及生态环境退化明显.(3)研究区RSEI值整体偏低且区域差异性显著,其中部地区是生态环境最为脆弱,北部忻州及南部临汾地区近年来生态环境退化尤为显著.(4)FVC变化趋势与RSEI变化趋势基本一致,FVC的增加对生态环境产生积极影响,而经济快速发展带来的道路、建筑用地、农田的增加对生态环境产生消极影响.区域扶贫发展的过程中应注意平衡经济发展与生态环境保护间的关系,避免进一步损害该区脆弱的生态环境.
