摘要:

分析生物多样性、土壤肥力、水源涵养、固碳能力等4种生态系统服务间的权衡与协同关系,从而为大青山植被合理经营提供理论依据。以内蒙古大青山白桦(Betula platyphylla)天然次生林、华北落叶松(Larix principis-rupprechtii)人工林、虎榛子(Ostryopsis davidiana)天然灌丛和天然草地等4种植被类型为研究对象,利用均方根偏差(RMSD)对区域生态系统服务的权衡与协同关系进行了研究,并对各生态系统服务的贡献进行了分析。结果表明,4种植被类型生物多样性为:白桦天然次生林 (2.81)>虎榛子天然灌丛 (1.84)>华北落叶松人工林 (1.80)>天然草地 (1.78);土壤肥力为:白桦天然次生林 (71.14 g∙kg-1)>华北落叶松人工林 (57.01 g∙kg-1)>虎榛子天然灌丛 (52.50 g∙kg-1)>天然草地 (35.58 g∙kg-1);水源涵养为:白桦天然次生林 (618.42 t∙hm-2)>华北落叶松人工林 (603.30 t∙hm-2)>虎榛子天然灌丛 (573.85 t∙hm-2)>天然草地 (561.02 t∙hm-2);固碳能力为:华北落叶松人工林 (468.92 t∙hm-2)>虎榛子天然灌丛 (415.31 t∙hm-2)>白桦天然次生林 (291.97 t∙hm-2)>天然草地 (129.37 t∙hm-2)。4种植被类型生态系统服务之间均属于权衡关系,其中白桦天然次生林的生物多样性分别与水源涵养、土壤肥力和固碳能力呈中等程度的权衡(ERMSD=0.149、0.159、0.145),表现为水源涵养具有较高的收益。华北落叶松人工林的固碳能力与生物多样性、水源涵养和土壤肥力呈较高程度的权衡(ERMSD=0.214、0.183、0.184),表现为固碳能力具有较高的收益。各植被类型的4种生态系统服务存在一定差异,白桦天然次生林的水源涵养能力强于其他生态系统服务,华北落叶松人工林的固碳能力占重要地位。由此可知,适当调整经营措施,提高人工林的生物多样性,同时注重改善天然林的固碳能力,可维持内蒙古大青山森林生态系统服务的平衡发展。

Abstract:

This study analyzed the trade-offs and synergies among four ecosystem services of biodiversity, soil fertility, water conservation, and carbon sequestration capacity to provide a theoretical basis for the rational management of vegetation in Daqing Mountain. Taking four vegetation types including Betula platyphylla natural secondary forest, Larix principis-rupprechtii plantation forest, Ostryopsis davidiana natural shrub forest and Natural grassland in Daqing Mountain, Inner Mongolia as the research objects, the trade-offs and synergies of regional ecosystem services were studied by using the root mean square deviation method (RMSD), and the contribution of each ecosystem service was analyzed. We found that the biodiversity of the four vegetation types was as follows: Betula platyphylla natural secondary forest (2.81)>Ostryopsis davidiana natural shrub forest (1.84)>Larix principis-rupprechtii plantation forest (1.80)>Natural grassland (1.78). The soil fertility showed as follows: Betula platyphylla natural secondary forest (71.14 g∙kg -1)>Larix principis-rupprechtii plantation forest (57.01 g∙kg-1)>Ostryopsis davidiana natural shrub forest (52.50 g∙kg-1)>Natural grassland (35.58 g∙kg-1). The order of water conservation was Betula platyphylla natural secondary forest (618.42 t·hm -2)>Larix principis-rupprechtii plantation forest (603.29 t∙hm-2)>Ostryopsis davidiana natural shrub forest (573.85 t∙hm-2)> Natural grassland (561.02 t∙hm-2), and that of carbon sequestration capacity was Larix principis-rupprechtii plantation forest (468.92 t∙hm -2)>Ostryopsis davidiana natural shrub forest (415.31 t∙hm-2)>Betula platyphylla natural secondary forest (291.97 t∙hm-2)>Natural grassland (129.37 t∙hm-2). There was a trade-off relationship between ecosystem services of four vegetation types. Among them, the biodiversity of Betula platyphylla natural secondary forest had moderate trade-offs with water conservation, soil fertility, and carbon sequestration capacity (ERMSD=0.149, 0.159, 0.145), and Betula platyphylla natural secondary forest showed a higher benefit for water conservation. The carbon sequestration capacity of Larix principis-rupprechtii plantation forest showed a high degree of trade-off with biodiversity, water conservation, and soil fertility (ERMSD=0.214, 0.183, 0.184), and Larix principis-rupprechtii plantation forest had a higher benefit for carbon sequestration capacity. The four ecosystem services of each vegetation type differed to some extent, with the Betula platyphylla natural secondary forest having a stronger water-holding capacity than the other ecosystem services, and the carbon sequestration capacity of Larix principis-rupprechtii plantation forest occupying an important position among the four ecosystem services. Therefore, the balanced development of forest ecosystem services in Daqing Mountain, Inner Mongolia can be maintained by properly adjusting management measures, improving the biodiversity of planted forests, and focusing on improving the carbon sequestration capacity of natural forests.
