滨海重盐渍荒漠化地区生态重建生物技术模式的研究——以天津滨海新区为例

Study and Application of Biotechnology Mode of Eco- reconstruction in Coastal Heavy Salty Deserted Land— — Take Tianjin Coastal Area for Example

通过对天津经济技术开发区自然地貌的分析,根据荒漠化的新概念,判定该区为典型的滨海重盐渍荒漠化地区,是滨海新区的代表。依据生态重建的相关理论,确定生态重建的技术体系,其中以引种、筛选耐盐植物和培育转基因耐盐植物的生物技术为关键技术。依此在该区域建立了海挡护坡和高速公路的耐盐植物生态景观模式。

Tianjin Economic & Techonlogy Developing Area, a typical example of Tianjin Coastal Area, is determined as a heavy salty deserted land according to the analysis on its natural physiognomy and the new concept of desertification. It is essential and important to reconstruct the ecology in this area for its special economic status. According to the related theories of eco- reconstruction, we establish the technology system of eco- reconstruction, among which biotechnology mode is an effective, directive and practical mode that adapts to our national present status and should be popularized and advocated in 21st century. The species introduction, salt- tolerant plants selection and transgenic salt- tolerant plants breeding are core biotechnologies. An ecological landscape mode of salt- tolerant plants along the expressway and bank- protecting slope should be built in the coastal area based on these technologies.
