以内蒙古大青山华北落叶松人工林为研究对象,利用树木年轮学和解析木法,推算过去41年人工林净初级生产力的年际变化,分析净初级生产力与气温、降水、湿度等因子的关系。结果表明:净初级生产力年际差异较大,总体上呈现出波动性的先增加后减小的趋势,净初级生产力多年平均为3.83 t/(hm2·a),最高为6.93 t/(hm2·a)。净初级生产力与上一年6月、11月、当年6—8月的降水显著相关;与上一年11—12月、当年2月和12月的大气相对湿度显著负相关;与上一年9月、7月、当年2月、8—9月的平均气温,以及与上一年11—12月、当年12月的平均气温和平均最高温度均呈显著或极显著正相关。总体来看,生长季的降水和气温、冬季的气温和湿度,即气温决定的生长季长短、降水决定的土壤水分、冬季温湿度决定的冻害是影响初级净生产力的主要因素,在未来该地区温度升高、降水增加的趋势下华北落叶松林生产力可能会增加。

Taking larch(Larix principis-rupprechtii) plantation in Daqing Mountain of Inner Mongolia as the research object,net primary productivity (NPP)of larch plantation in the past 41 years was calculated by dendroecological methods and biomass-DBH equations,and the relation between NPP with climatic factors,including precipitation,temperature and humidity was analyzed.The results indicated that the interannual variation of NPP of the plantation showed a trend of increasing at first and then decreasing,and mean NPP of the stand was 3.83t/(hm2·a),with a maximum value of 6.93t/(hm2·a).The NPP was closely correlated with climatic factors.The NPP of larch plantation was significantly correlated with the monthly precipitation in June and November of previous year andthat fromJune to August of currentyear.It was negatively correlated between NPP with the relative humidity in December,February of the previous year and February and December of current year.The NPP was correlative significantly positively with the monthly mean temperature in September of both previous and current year,June of previous year and February and August of current year.The monthly mean temperature and monthly mean maximum temperature in November and December in previous year and Decemberin current year also significantly affected NPP.Generally,precipitation and temperature in growing season,temperature and humidity in winter,that is,the length of growing season determined by temperature,soil moisture in growing season determined by precipitation,and freezing damage determined by temperature and humidity in winter,are main factors of larch forest NPP.It is implied that the larch plantations NPP would present an increasing trend in the future due to the warmer and more humid climate condition in the research region.
