摘要/Abstract

摘要： 草地植物群落的物种组成变化影响草地土壤养分数量和分布格局,而土壤理化性质改变会加速原生植物被更适生于此土壤条件下的植物所代替。狼毒在退化草地中斑块状集群分布的格局可能会影响草地植物的群落结构和土壤养分循环过程。以退化草地中未防除狼毒和防除狼毒的狼毒斑块为研究对象,分析斑块内和斑块间草地植物群落的特征和土壤养分含量变化规律。结果表明: 1)未防除狼毒和防除狼毒斑块间的地上生物量、丰富度指数和Shannon-Wiener多样性指数显著低于未防除狼毒斑块内,而防除狼毒斑块内和斑块间的地上生物量和群落多样性指数差异不显著; 2)未防除狼毒斑块内土壤含水量、有机质含量、全氮含量、速效磷含量、铵态氮含量显著高于斑块间;同时,未防除狼毒斑块内土壤含水量、有机质含量、全氮含量显著高于防除狼毒斑块内,而防除狼毒斑块内土壤速效钾含量显著高于未防除狼毒斑块内。由此可见,狼毒斑块内土壤养分和水分含量比斑块间高,表现出明显的“肥岛”效应。针对狼毒型退化草地治理应严格控制草地载畜量并辅以防除狼毒、围封、施肥等草地改良措施,实现狼毒型退化草地的可持续利用。

Abstract: Species composition of a grassland community has significant effects on soil nutrient contents and nutrient distribution. Under grazing pressure, native plant species may be replaced by invasive or toxic weeds highly adapted to the local soil type, resulting in degraded grassland. Stellera chamaejasme is one such invasive species that has become the dominant species in degraded grassland in parts of the Qinghai region, where it is often found with patchy distribution within stands of other plant species. However, few studies have examined the effects of S. chamaejasme patches on the surrounding grassland community or on soil physical-chemical properties in degraded grassland of Qinghai-Tibet Plateau. Therefore, aboveground biomass, diversity indexes and soil nutrient contents were measured within or between S. chamaejasme patches in natural grassland or after herbicide treatment. It was found that aboveground biomass, species richness index and Shannon-Wiener index were significantly lower between patches than within patches untreated with herbicide. However, after herbicide application, the aboveground biomass and diversity indexes did not differ between and within S. chamaejasme patches. Meanwhile, soil water content, organic matter content, total nitrogen, available phosphorus, and NH4+-N contents were significantly higher within patches than between unsprayed patches. In addition, soil water, organic matter, and herbage total nitrogen contents within unsprayed patches were higher than within herbicide sprayed patches. However, available potassium content was higher within, than between patches receiving herbicide, Therefore, soil water and nutrient within-patch were higher than between-patch, demonstrating that S. chamaejasme patches had characteristics of a “fertile island”. Effective restoration of degraded S. chamaejasme grassland should include improvement measures, such as control of grassland carrying capacity, weed control, fencing and fertilization. With such measures in place, ecologically sustainable development of grassland where S. chamaejasme is present, can occur.

Key words: Stellera chamaejasme, patch, diversity index, soil nutrient, fertile island, herbicide
