By applying the theory of dissipative structure, this paper researches the temporal series and the spatial structure of the reversion process of desertification, and discusses the fluctuations, formation of the dissipative structure, and unbalanced phase change in the reversion process of desertification. It is pointed out that, as an open system, the reversion process of desertification has an orderliness in temporal series, but an un-orderliness in spatial structure, which is a process from the un-orderliness...

By applying the theory of dissipative structure, this paper researches the temporal series and the spatial structure of the reversion process of desertification, and discusses the fluctuations, formation of the dissipative structure, and unbalanced phase change in the reversion process of desertification. It is pointed out that, as an open system, the reversion process of desertification has an orderliness in temporal series, but an un-orderliness in spatial structure, which is a process from the un-orderliness to the orderliness under the multi-dissipative structure, and has a self-regulation capability under the special conditions. Therefore, in this tridimensional, dynamical and open system jointly composed of the natural environment, living things and humanity, there is not only the entropic increase mechanism of the second law in thermodynamics, but also the inherent negative entropic increase mechanism in biology, the entropic increase represents the desertification process, and the negative entropic increase represents a reversion process of desertification. These provide a new theory for researching the relationships between the balanced stability and orderliness and the unbalanced stability and orderliness, deterioration and reversion, effect of single factor and joint effect of multiple factors, and parts and whole. Moreover it is considered that the conception of the theory of dissipative structure contributes to developing desert ecology related to the "process" so as to enrich the theoretical significance of desertification research.

用耗散结构理论探讨了沙漠化逆转过程的时间序列和空间结构 ,论述了沙漠化逆转过程中的“涨落”现象、耗散结构的形成及非平衡相变的发生。指出属于开放系统的沙漠化逆转过程表现为时间序列的有序和空间结构的无序 ,是多重耗散结构下的从无序到有序的过程 ,并在特定的条件下具有自我调控的组织能力。熵增代表着沙漠化过程 ,负熵增代表着沙漠化逆转过程。这对研究沙漠化过程的平衡稳定有序与非平衡稳定有序的关系 ,恶化与逆转、单因素与综合、部分与整体的关系提供了新的理论武器 ,并认为耗散结构理论的思想有助于建立一门有关“过程”的沙漠生态学 ,以丰富沙漠化研究的理论意义。

The long-term located experiment has been conducted on the grey desert soil in the Fukang Desert- Ecology Station in Xinjiang since 1991 with the purpose to investigate the dynamic changes of 15 indicators of soil quality. The results showed that there were great differences of physical and chemical characters among different treatments. Through principal components analysis, three factors were determined for 88.9% of the variance interpretation. The 15 evaluation indicators could be divided into 3 principal components: the first was organic matter mineralization factor which had a positive loading on nutrition level, enzyme activity and crop yield; the second was soil potassium factor which had a positive loading on total K, available K, CEC and urease activity; the third was soil phosphorus factor which had a positive loading on total P and available P. According to the comprehensive factor scores, the effect of combination application of organic manure and chemical fertilizers were superior to single chemical fertilizers in improving the activities of soil enzyme and nutrients.

自1991至今,在新疆阜康荒漠生态站进行长期定位施肥试验,对灰漠土上9种不同施肥处理后土壤的15项理化指标进行了测试。结果表明,不同处理后土壤的理化性质差异较大,说明不同施肥方式有各自的优缺点;并用SPSS统计软件,采用因子分析的方法对实验结果进行综合分析:由于前三个主分量的累积贡献率达到88.9%,15个评价指标被划分为三个主分量,第一主分量为影响作物产量的有机质(氮)矿化有关的供氮指标,第二主分量为影响钾的容量指标,第三主分量为土壤的磷素指标。并根据因子综合得分得出:施用N2P2K、N1P1K+秸秆、N1P1K+猪粪对改良灰漠土的效果最好,是本区应大力推广的施肥方式。
