摘要: 大兴安岭北部森林覆盖区内白桦、落叶松分布广泛。以白桦、落叶松作为植物化探的主要研究对象具有可操作性和可推广性.植物的外皮、落叶是植物化探研究的首选.落叶松、白桦树叶的采集时间应在9月份叶落后不久，采样间距可在100~600m之间.松树、白桦树皮的采样时间集中在6月和9月两个阶段，采样间距在10~200m之间，采集的树皮距地约0.2m.建议采用干灰化法，最佳的灰化温度在450℃左右

Abstract: Betula and larix are broadly distributed in the forest covered area in northern Daxing'anling Mts.The botanogeochemical study by taking betula and larix samples is operatable and versatile.The outer barks and fallen leaves of plants are the best sampling media for botanogeochemical survey.The sampling for larix and betula leaves should be done in September,when the leaves have just fallen down.The interval of sampling is between 100 and 600 m.The best sampling periods for larix and betula barks are June and September.The sampling interval should be 10~200 m.The sampled barks would be 0.2 m above the ground.Dry ashing is suggested.The best ashing temperature is around 450℃.
