不同经营方式马尾松人工林土壤截持降水能力及调控因素
Soil Interception Capacity of Pinus massoniana Plantation with Different Management Modes and Its Controlling Factors
[目的]明确区域尺度上不同经营方式人工林的土壤截持降水能力及其驱动因素对人工林管理及水土保持至关重要。[方法]在中国亚热带地区(广东肇庆、湖南会同和湖北秭归),基于氢稳定同位素技术探讨了不同量级降水(小雨、中雨和大雨)对不同经营方式马尾松人工林(纯林、混交林、除灌林、轻度间伐林及重度间伐林)土壤水的贡献率。进一步地,我们基于方差分解和结构方程模型等方法揭示了影响降水对土壤水贡献率(CRSW)的主要因素。[结果]不同降水条件下,各经营方式马尾松人工…查看全部>>
[Objective]It is very important for plantation management and soil and water conservation to make clear the soil interception and precipitation capacity and its driving factors of plantations with different management modes on regional scale.[Method]Based on the hydrogen stable isotope technique,the contribution rates of precipitation of different magnitude(light rain,moderate rain and heavy rain)to soil water of Pinus massoniana plantations with different m…查看全部>>
