摘要
【目的】研究经济林资源动态变化,为指导区域林业生产、科学规划、合理经营、稳定发展提供科学理论依据。【方法】选取新疆叶城县代表性的核桃、红枣、杏、石榴、苹果、香梨、葡萄、桃等经济林树种,利用“3S”技术,数集2004、2014年实地调查数据,运用数理统计与空间分析方法,分析叶城县经济林资源树种、品种、面积的时空变化及分布特征。【结果】2004~2014年间,叶城县经济林中核桃增长面积最大,为25225.74hm2,年平均变化率为19.02%;第二为红枣,面积为1382.92hm2,年平均变化率为1398.30%;杏、石榴、苹果等面积均呈现不同程度的减少。【结论】叶城县林果业发展模式较单一,经济林以核桃为主,增长面积远超其他经济林品种,且在时间和空间上均呈现不平衡分布。
【Objective】 This project aims to grasp dynamic changes of economic forest resources and put forward the solutions to the imbalance of economic forest distribution in Yecheng County in the hope of providing a scientific theoretical basis for guiding regional forestry production, scientific planning, rational management and stable development.【Method】'3S' technology was used for field data collection to select representative walnut, red dates, apricots, pomegranate, apples, pears and grapes in Yecheng County. The field survey data of economic forest trees and peaches in 2004-2014 were analyzed by using mathematical statistics and spatial analysis methods to explain the temporal variation and spatial distribution characteristics of economic forest tree species and variety area in Yecheng County.【Result】 In Yecheng County from 2004 to 2014, the largest growth area of walnut was 25,225.74 hm 2, the annual average rate of change was 19.02%. The growth area of jujube was the second largest at 1,382.92 hm 2, and the annual average rate of change was 1,398.30%. The area of apricot, pomegranate, apple and other trees showed varying degrees of reduction.【Conclusion】 The development model of forest fruit industry in Yecheng County is singular. The main economic forest varieties are mainly walnuts, and the growth area is far superior to other economic forest varieties, and they are unevenly distributed in time and space.
