The process of ecological degradation in the vicinity of Shaoguan Pb/Zn smelter may be summed as: heavy metals and acidic deposits from the waste gas from smelter resulted in the vanishment of the sensitive plant species, increasing accumulation of heavy metals in soils and acidification of topsoil worsened the chemical properties and then shallow-rooted plant, mainly the herbaceous, vanished. With the demolishment of the vegetation cover, increasing water-soil erosion worsened physico-chemical properties of soil and, subsequently, some woody plants disappeared and barren land was finally appeared.

该生态系统的退化过程可以归纳为：来自于冶炼废气的重金属和酸沉降导致了敏感植物的消亡，丧失了对土壤的缓冲保护作用；重金属在土壤表层的积累，酸性物质在土壤表层的增加导致的土壤酸化以及由此引发的有机质与养分的淋溶和重金属及Al的活性增加，加剧植被的快速退化，特别是浅根植物的衰亡；地被层的破坏，导致水土流失和土壤侵蚀加深，进一步恶化表层土壤的理化性质，一些木本植物随之消失，最终形成光板地。

综上所述，在目前的研究背景下简单地用经典的归纳学习算法进行学习来构成模式识别用的分类器是不审慎的，因为构成具有高判决精度的分类器是模式识别的最终目的；而如果不加考虑地任意采用一种现成的决策森林算法或多变决策树算法来解决实际问题也不一定就能取得更理想的效果。

This thesis analyzes the types and art trait of solar-assisted heat pump water heater, the development trend of direct expansion solar-assisted heat pump water heater, makes a summary of these research results from six aspects. On the basis of these works and from the point of view of receiving optimum solar radiation , the thesis develops a novel design model of direct expansion solar-assisted heat pump water heater with a truncated cone collector/evaporator, theoretically analyzes the heat that the system can absorb, compares its ability with other two types of cylinder and flat plate ones, and calculates COP and EER with computer aids. The results show that a truncated cone direct expansion solar-assisted heat pump water heater can absorb not only more solar energy but heat energy in air. It takes on favorable thermal performance. Under the average day in February which is of the worst weather throughout the year in Kunming, the COP is about 4. 2, EER is about 2.9 . The heat absorbed by the system are more than those of the other systems. The system is very great in terms of saving

本文分析研究了太阳能热泵热水系统的分类及技术特点，直膨式太阳能热泵技术国内外发展趋势，从六个方面对直膨式太阳能热泵热水系统的研究进行了归纳总结；在此基础之上，从太阳辐射的最佳接收考虑，提出了集热器／蒸发器为圆台侧面的圆台型直膨式太阳能热泵热水器的设计模型，理论上分析了这种热水系统所接收的太阳辐射和得热量，并与圆柱型、平板型的直膨式太阳能热泵热水系统进行对比分析，通过计算机辅助模拟计算出：系统不但可以有效地吸收太阳能，还能有效地吸收空气中的热量，具有良好的热性能；在昆明，以2月为代表的冬季，其太阳辐照较低，系统的制热系数COP值也能达到4.2，效能比EER值为2.9；系统的得热量高出圆柱型、平板型的直膨式太阳能热泵热水系统，节能效果明显。
