- 摘要:
- 以雅江县为研究对象,基于土地利用数据、高程数据、林业二调数据、土壤数据、气温降雨数据,采用GIS空间分析方法,研究松茸在雅江县的适宜分布区域,并对研究结果进行野外验证并修正。结果表明:雅江适宜松茸生长的区域面积约370.08 km2,占县域面积的4.88%,主要分布在河口镇、八脚楼乡、呷拉镇、米龙乡等区域;另适宜区分级结果表明松茸生长的适宜区、较适宜区、最适宜区面积分别约为4.32、291.36、74.40 km2,分别占适宜区总面积的1.17%、78.73%、20.10%。该研究结果对区域松茸的合理保护与利用具有重要意义。
- Abstract:
- Yajiang county was used as an example,based on the land use data,elevation data,forestry resources investigation data,soil data,temperature and rainfall data,using spatial analysis method in GIS to analyze the suitable distribution areas of Tricholoma matsutake,conducted a field validation of the results and corrected them.The results showed that Tricholoma matsutake resources were mainly distributed in Hekou town,Bajiaolou town,Gala town,Milong town and so on,and the suitable areas for Tricholoma matsutake′s growth were about 370.08 km2 in Yajiang county,which was accounted for 4.88% of the total county area.Moreover,this study divided the suitable distribution areas of Tricholoma matsutake into three types:suitable areas,the more suitable areas,most suitable areas,and the area of them were 4.32 km2,291.36 km2,74.40 km2,which were accounted for 1.17%,78.73%,20.10% of the total suitable area.The results could provide reasonable basis for Tricholoma matsutak′s protection and utilization.
