中文摘要: |
以福建省现状林地、园地、草地和部分未利用地为研究对象,根据花榈木、红豆树、降香黄檀3 个
豆科珍贵树种生长的立地要求,从地形、气候、土壤和社会经济4 个方面选取评价因子,借助GIS 技术和修正
的加权指数及模型对福建省豆科主要珍贵树种进行用地适宜性评价。在此基础上,屏蔽不适宜用地,基于“适
地适树”的用地优化布局理念,采用优势适宜性指数和K 均值聚类分析相结合的方法,开展福建省豆科主要
珍贵树种用地优化布局研究,将花榈木、红豆树和降香黄檀适宜用地分别划分为优先种植区、次优先种植区和
一般种植区3 个等级,制作福建省豆科主要珍贵树种用地优化布局图,并进行分区评述。 |
英文摘要: |
Based on the demands of precious legume forest species,such as Ormosia henryi,O. hosiea and
Dalbergia odorifera habit and taking the woodland,orchard,meadow,and some unused land in Fujian as the research
object,a suitability evaluation index system of precious legume forest species was established. The index system
included 14 relevant factors form four aspects: topography,climate,soil and social economic. Suitable land resources for
precious legume forest species were assessed by GIS technology,integrated with correctional weighting-multiplication
model. On this basis,non-planting areas were extracted from the land-use map,the layout of precious legume forest
species in Fujian was optimized based on the principle of"suitable trees plantation on land"with integrated technology
of the advantages of index method and K means clustering analysis method. The results of regionalization included three
grades of preferential planting area,secondary preferential planting area and general planting area. The results of above
partitions were analyzed and optimizing arrangement map of precious Legume species plantation in Fujian was drew by
GIS technology. |
