为探讨哈尼梯田生态系统天人合一的水分和营养元素的利用模式,揭示哈尼梯田生态系统氮素时空变化规律,明确土地利用对氮浓度的影响,为哈尼梯田的水环境保护和可持续发展提供科学依据。以元阳县全福庄小流域为研究对象,应用Kriging空间插值法分析了该系统地表水氮素的时空分布特征。结果表明:(1)除NO3--N浓度在夏季和冬季呈强变异外,其他N浓度在不同季节的变异系数均小于100%,表现为中等程度变异。(2)梯田中下部TN、NO3--N和NH4+-N浓度变幅都较大,分别为0.103~0.849,0.010~0.143,0.052~0.446 mg/L,森林地表水中TN、NO3--N和NH4+-N浓度的变幅都相对较小,分别为0.108~0.471,0.003~0.102,0.058~0.164 mg/L。(3) TN、NO3--N和NH4+-N各季节的块金系数均小于50%,各季节均有较强的空间自相关性。TN、NO3--N和NH4+-N各季节的变程均在1 000 m以内,表明各指标各个季节分别在不同尺度范围内分布连续,存在空间自相关性。(4)通过Kriging插值法得知,不同季节TN、NO3--N,NH4+-N地表水浓度从整体上为村庄>梯田>河流>森林的分布规律。
To explore the unity use patterns of water and nutrients in Hani terrace
reveal the spatial and temporal variation of nitrogen
clarify the impact of land use on nitrogen concentration
and provide scientific basis for water environment protection and sustainable development
we used QuanFu zhuang watershed as the research object
analyzed the characteristics of spatial and temporal distribution of surface water nitrogen. The research showed that (1) Except for the strong variation of NO3--N concentration in summer and winter
the coefficients of variation of other N concentrations in different seasons were less than 100%
and showed a moderate variation. (2) The variations of the concentration of TN
NO3--N and NH4+-N concentration in the lower part of the terraced fields were (0.103~0.849
0.010~0.143
0.052~0.446 mg/L) relatively large
and the variations of the concentration of TN
NO3--N and NH4+-N concentration in forest surface water were (0.108~0.471
0.003~0.102
0.058~0.164 mg/L) relatively small. (3) The nugget coefficients of TN
NO3--N
and NH4+-N were less than 50% in each season
and showed a strong spatial correlation in each season. The variation ranges of TN
NO3--N
and NH4+-N were all within 1 000 m in each season
indicating that the variation was distributed continuously in different scales in each season and there was spatial autocorrelation. (4) Through Kriging interpolation
the overall TN
NO3--N
and NH4+-N concentration in surface water of different seasons ranged as village > woodland > terrace > rivers.
