摘要
南方红豆杉是具有重要生态和经济效益的珍稀濒危植物,研究用地优化布局对南方红豆杉的保护和发展工作具有重要意义。本研究以福建省现状林地为研究对象,根据南方红豆杉生长的立地要求,从地形、气候、土壤和社会经济4个方面选取评价因子,在开展南方红豆杉用地适宜性评价的基础上,基于“适地适树”的用地优化布局理念,借助GIS技术进行南方红豆杉用地优化布局。结果表明:福建省南方红豆杉适宜用地面积占评价对象总面积的44.83%,其中高度、中度适宜用地分别占全省南方红豆杉适宜用地总面积的31.31%和59.88%。全省南方红豆杉优先种植区面积为279.72万hm^(2),主要分布在三明市的尤溪、永安、大田、清流、明溪和将乐,南平市的延平、建瓯、顺昌、建阳、政和和邵武,龙岩市的漳平、新罗、武平、连城、上杭和长汀,泉州的德化,福州市的永泰和闽清等县(市、区),可作为福建省优先发展南方红豆杉生产的重点区域。
Taxus mairei is a rare and endangered plant with important ecological and economic benefits.It is of great significance to the protection and development of the tree that research on the optimized arrangement of land suitability.Based on the demands of Taxus mairei,taking the woodland in Fujian as the research object,a suitability evaluation index system of it was established.The index system included 15 relevant factors of four aspects:topography,climate,soil and social economic.Suitable land resources for Taxus mairei were assessed by GIS technology,integrated with correctional weighting-multiplication model.Then,non-planting areas were extracted from the land-use map,the layout of the tree in Fujian was optimized based on the principle of“suitable trees plantation on land”with integrated technology of the advantages of index method.Results showed that the suitable land area for Taxus mairei planting in Fujian accounted for 44.83%of the total area of the evaluation object,including 31.31%was high suitability,and 59.88%moderate in suitability.The land resources in the“first suitable planting area”category were mainly distributed in fine regions,such as Youxi,Yongan,Datian,Qingliu,Mingxi,Jiangle,Yanping,Jian'ou,Shunchang,Jianyang,Zhenghe,Shaowu,Zhangping,Xinluo,Wuping,Liancheng,Shanghang,Changting,Dehua,Yongtai,Minqing and other counties(cities,districts),totaling up to 27972 km^(2) of the category,could be planning as key developing area for Taxus mairei.
