本文旨在揭示东北北部平原区湿地资源在不同经营方式下的开发利用途径。通过试验,对湿生系统和旱生系统两种经营制度的对比分析,结果表明:湿生系统在物质能量转换及养分循环等方面优于旱生系统,这对该地区传统的湿地旱作观念提出了挑战——湿生农业生态系统可作为该地区湿地资源开发利用的有效途径之一。
The purpose of this paper is to reveal the ways to exploit and utilize wetland resources in the plains of northern Northeast under different management modes. The results of comparative analysis of two operating systems of wetland system and xerophytic system show that wetland system is superior to xerophytic system in material energy conversion and nutrient cycling, Raises the challenge that wetland agroecosystem can be used as an effective way to develop and utilize wetland resources in this area.
