油棕在云南保山干热河谷区引种适应性初步评价Preliminary evaluation on adaptability of the introduced oil palm in dry-hot valley of Baoshan, Yunnan province

open access: yesZhongguo youzhi, 2022
为评价油棕在干热河谷地区的生长表现,于2011年从海南引进‘热油2号’‘热油4号’‘热油6号’和‘热油8号’4个油棕品种在云南保山干热河谷区试种,并按照农业农村部油棕品种区域适应性试种观测相关技术规范开展抚管和观测。经过多年引种观察,4个油棕品种在云南保山干热河谷区均能正常生长发育,表现出较强的适应性,其中‘热油2号’株高、茎高、年新增叶片数、冠幅生长量最大,‘热油4号’果穗性状、果实性状表现最优,可作为生产上小规模试验性试种材料推广种植。 To evaluate the growth ...

金沙江干热河谷退化山地径流塘—草网络技术研究初报

open access: yesShuitu Baochi Xuebao, 2002
金沙江干热河谷植被恢复的主要障碍是土壤干旱和以有机质为主的养分缺乏,由此造成人工植被成活率低或生长不良。针对这一因子,借鉴国内外干旱地区微区集水技术经验,结合金沙江干热河谷退化山地年均降雨600mm左右,地方乡土草黄茅(Heteropogoncontortus)人为目的干预下生长良好的实际,设计了山地径流塘-草网络技术。试验研究表明:径流塘-草网络技术具有固土稳水功能,可增强乔木树微区环境土壤抗蚀性能,改善以有机质为主的养分条件及树根区的土壤水分条件,致使研究区内的乔木经济树种酸角 ...

基于GIS的干热河谷植被恢复分区研究——以攀枝花城市视野区为例

open access: yesShuitu Baochi Xuebao, 2003
以攀枝花视野区为例,研究了基于GIS的干热河谷区植被恢复适宜性评价及分区方法.在干热河谷植被恢复适宜性评价及分区中,主要考虑对植被类型及植物生长影响较大的海拔高度、坡向、坡度、岩土类型、土层厚度等因素,并采用专家评分法给各影响因子权重和适宜性评价赋值.经过GIS的数据处理、空间分析、模型建立及运算,得到植被恢复适应性评价图,再经过分类、合并,将攀枝花市视野区划分为适宜区、较适宜区、较不适宜区、不适宜区、极不适宜区,得到植被恢复分区图.
