| 8. | The results were summarized as follows : ( 1 ) there were significant temporal - spatial differences in carbon sources and sinks among different costal regions
通过研究，得到了以下几点结论： ( 1 )沿海地区农田生态系统碳源汇的时空差异显著。 |
| 9. | It meant that carbon emission was obviously less than carbon absorption in costal regions . for example , carbon absorption was about 3 times more than emission in 2001
就目前来说，农田生态系统碳排放明显低于碳吸收，如2001年的沿海地区农田生态系统碳吸收为碳排放的4倍左右。 |
