中国竹类多样性、地理区划及发展趋势

文章分析了中国竹类物种资源现状及其自然地理区划，并探讨了竹资源未来的发展趋势。结果表明：截至2022年6月底，中国有竹类植物47属770种55变种251栽培品种；天然竹林根据自然地理分布可以区划为4个区：丛生竹区、混合竹区、散生竹区和亚高山竹区；其中，丛生竹区又可分为东南季风丛生竹亚区和西南季风丛生竹亚区2个亚区，散生竹区又可分为降水性散生竹亚区和灌溉性散生竹亚区2个亚区。中国竹资源发展将呈现如下变化趋势：1)野生竹种的数量增长不大；2)竹品种数量将较快增加；3)野生竹林将受到严格保护；4)人工竹林将有序增加；5)竹资源管理与利用将更加科学。

Bamboo Resources in China:Species Diversity,Geographical Zoning and Development Trend

This paper analyzes the present situation of bamboo resources and their natural geographical zoning in China,and discusses the future development trend.The results show that by the end of June 2022,there are 251 cultivars,55 varieties,770 bamboo species and 47 genera of Bambusaceae in China.The natural bamboo forest in China can be divided into four zones according to natural geographical distribution,i.e.,sympodial bamboo zone,sympodial and monopodial mixed bamboo zone,monopodial bamboo zone and subalpine bamboo zone;among them,the sympodial bamboo zone can also be divided into two sub-zones of the southeast monsoon sub-zone and the southwest monsoon sub-zone,and the monopodial bamboo zone can also be divided into two sub-zones of the precipitation sub-zone and the irrigation sub-zone.China will see the future development trend of bamboo resources as follows:1) The number of wild bamboo species will not increase greatly;2) The number of bamboo cultivars will increase rapidly;3) Wild bamboo forests will be strictly put under protection;4) Artificial bamboo forests will increase in an organized way;and 5) Bamboo resources management and utilization will be more science-based.
