本論文依託巫溪縣水土保持生態修復項目，運用模糊層次分析方法，進行退化生態系統的景觀健康評價體系設計與健康等級分析；通過對比研究巫溪縣與另一個生態修復試點縣? ?璧山縣的土地景觀空間格局分析，揭示巫溪縣土地利用格局上的退化特徵；提出與水土保持治理相結合起來的生態恢復模式；引用土壤肥力質量指數，對生態修復區不同生態恢復演替階段群落及不同時期坡改梯、休耕地與封山育林三項生態修復措施的土壤肥力質量分析與對比。This is a newly introduced slight shocking, direct driving centrifugal hyro - extractor. the electric locomotive on its base is semi - closed, internal ventilating, self cooling, weight adding and energy saving. the internal drum and rotational drum are istalled on the axel of the locomotive and drived directly, which effectively decreases energyloss, and simplifies therotation. acontrolling box is used in the machine to start through frequency conversion. and stop through resistance. the showing board shows the rotation speed and adjusts the speed and time. the featues of this machine areenergy saving, durable and repair infrequent. this machine is spcially used for cloth hydroectraction
本機系最新引進直微震直驅式離心脫水機，它使用半封閉內通風自冷加重型專用節能電機裝于中間底座，內桶及轉鼓裝于電機軸而直接驅動之，有效地減小了多功能損耗，簡化了傳統的多級繁瑣轉動，本機配有一個電控箱機變頻起動，電阻剎車於一體面板有轉速顯示並可調速度及時間，該機特點省電、耐用、維修機會極少，本機適合布匹脫水使用。Fcd. 3 138g : 4ds outer - thread copper pipe union at both ends of the inlet and the outlet this valve uses the principle of two - stage pressure reducing variation and, when to lower the switch valve, the shock from the water pressure to the valve casing shortens the start time of this valve under the highest medium pressure and makes it with the incomparable superiority of energy saving among the pulse - type electric - controlled valves, combining to increase filtered to regulate the discharge function with machine type
該閥採用二級減壓變化原理，降低開關閥時水壓對閥體等配件的沖擊，提高電磁閥的可靠性和工作壽命，縮短了閥在最高介質壓力下開啟時間，使其在脈沖式電控閥門中具有無可倫比的節能優勢，並在接線上採用密封插件，並增加了過濾器和機械式調節流量功能。
