修复植物地上部对污染土壤中重金属离子的转运能力是决定修复效率关键要素之一。目前发现的非典型重金属积累植物普遍存在地上部对离子转运能力甚低（S/R=0.5左右），致大部分离子存储于根部远不能达到有效净化修复目的难题。以公认重金属超积累植物天蓝遏蓝菜(Thlaspi caerulescens)为代表虽存在植株生物量小生长缓慢等不足，但地上部对离子的转运能力很强（S/R>1）。目前对天蓝遏蓝菜已有诸多研究报道，但关于地上部超强转运离子动力以及发生理论等并没有给予科学回答。本研究以天蓝遏蓝菜为材，选择重金属Cd2+离子胁迫，定位于地上部离子超积累组织细胞学‘库’位，引入生物酶化学动力发生理论研究方法，探究并验证植物体内外离子超强转运且‘库’积累发生可能的内在动力源及其动力发生机制，旨在探明金属离子发生‘库’积累的关键物质及其动力发生学机理，为今后进行修复植物高效遗传改良与创新种质研究提供科学依据。

The translocation ability of heavy metals in the contaminated soil to the aboveground part of remediation plants is the key factor of the phytoremediation efficiency. It is far from the purify the remediation purpose because the most heavy metals are accumulated in the underground parts of the well known remediation plants and only a little translocated to the aboveground parts of the atypical heavy metal accumulation plants（S/R=0.5 or so）. Although Thlaspi caerulescens L. is small plant biomass and slow growth, which is recognized as one of the model plants in translocation of most heavy metals in the aboveground part (S/R>1). There have been many reports on the research of Th. caerulescens. However, the strong translocation capacity and excessive accumulation of critical translocating power (source) of heavy metals to the ground part of Th. caerulescens and its inherent motivation theory still have not get the scientific answer and explanation. This study take Th.caerulescens as the experimental material, choose Cd2+ as stress factor, and take aboveground part of plant 'Cd2+ hypperaccumulation storage' as researching target. Meanwhile, the theory of enzyme chemical power is introduced in the research methods to investigate and verify the internal power source and its dynamic mechanism of 'Cd2+ hypperaccumulating storage' in the aboveground part of the plant. The purppose of the research is preliminary found out the key materials of 'Cd2+ hypperaccumulating storage' and its genetic mechanism of power generation. The results will be the scientific basis for the future studies of genetic improvement and germplasm innovation in the high efficiency translocation of heavy metals in phytoremediation.
