摘要
柞林与各类次生林、人工林平均值相比,其涵养水源功能可达61.5%,回归土壤N、P、K肥,分别多32%、35%、38%,碳汇与释氧功能分别高27.6%和27.8%。以柞林为主的森林公园内,负离子丰富,测定峰值达7 500个/cm2。柞林内食源丰富,是野生动物的首选栖息地。
Oak forest function is better than that of secondary forest and artificial forest, the water conservation function of soil conservation 61.5% ; returned to the NPK fertilizer from abundant litter, respectively 32%, 35%, 38% ; carbon and oxygen release respectively 27.6% and 27.8%. In oak forest park, determination peak of negative ion abundance was 7500 / cm2. Oak forest was the preferred habitat of wild animals because food source is rich in it
