Abstract : the restoration of the riparian vegetation disturbed by human activities is one of the hotspots of watershed ecology. through interpreting the images of remote sensing in 1985 and 1999, the basic information of forest resources of lushuihe forest bureau, which is a typical forest area of changbai mountain, was obtained with support of gis. by dividing land covers of lushuihe area into 10 types ( water body, residential land, stump land, farming land, wetland, mature conifer forest, midlife conifer forest, mature broadleaf forest, midlife broadleaf forest, and man - made young forest ) and dividing the riparian zone into four buffers ( in turn, 1000, 2000, 3000, 4000 m away from the river ), the changes of riparian forest resources during 1985 - 1999 were analyzed. the results showed that the deforestation intension has obviously decreased and the whole environment has been evidently improved, but the riparian ecosystem was still flimsy. in buffer 1, 2, 3, the area of midlife conifer forest increased largely, but the areas of other types of land covers all decreased. midlife conifer forest had a comparatively good status in the three buffers. in buffer 4, midlife conifer forest, mature conifer forest, and mature broadleaf forest formed a forest - age rank that is helpful to stabilize the forest ecosystem and exert its functions. area percentage of wetland decreased in buffer 1, buffer 2, and buffer 3, even in buffer 4 in which forest ecosystem rehabilitated comparatively well, so protecting and rehabilitating wetland is a very difficult task
文摘:本文對兩期遙感圖像進行解譯，並在gis支持下提取露水河林業局主要河流兩岸各緩沖區森林資源信息，經分析得到各類地物在1985年及1999年的變化趨勢.結果表明:在河流沿岸對森林的採伐強度1999年較1985年明顯減小，整體生態環境較1985年有所改善.在緩沖區1 ， 2 ， 3除中齡針葉林大幅度增加外，其它地物類型面積均減少，由此可以看出，在這三個緩沖區內針葉林得到了較好的恢復.在緩沖區4內，中齡針葉林、成熟針葉林、成熟闊葉林形成一個林齡梯隊，有利於森林生態系統的穩定與功能的發揮，十五年間緩沖區4受到的干擾相對較小.濕地數量在四個緩沖區內均有所減少，雖然在緩沖區4內森林生態系統恢復的較好，但濕地面積仍有所減少，說明保護及恢復濕地資源是一件非常艱巨的任務，必須引起高度重視.圖5表2參12The restoration of the riparian vegetation disturbed by human activities is one of the hotspots of watershed ecology. through interpreting the images of remote sensing in 1985 and 1999, the basic information of forest resources of lushuihe forest bureau, which is a typical forest area of changbai mountain, was obtained with support of gis. by dividing land covers of lushuihe area into 10 types ( water body, residential land, stump land, farming land, wetland, mature conifer forest, midlife conifer forest, mature broadleaf forest, midlife broadleaf forest, and man - made young forest ) and dividing the riparian zone into four buffers ( in turn, 1000, 2000, 3000, 4000 m away from the river ), the changes of riparian forest resources during 1985 - 1999 were analyzed. the results showed that the deforestation intension has obviously decreased and the whole environment has been evidently improved, but the riparian ecosystem was still flimsy. in buffer 1, 2, 3, the area of midlife conifer forest increased largely, but the areas of other types of land covers all decreased. midlife conifer forest had a comparatively good status in the three buffers. in buffer 4, midlife conifer forest, mature conifer forest, and mature broadleaf forest formed a forest - age rank that is helpful to stabilize the forest ecosystem and exert its functions. area percentage of wetland decreased in buffer 1, buffer 2, and buffer 3, even in buffer 4 in which forest ecosystem rehabilitated comparatively well, so protecting and rehabilitating wetland is a very difficult task

本文以黑龍江省信息產業廳專項基金課題? ?水泥企業通用型mis軟體的研發與應用為背景，結合浩良河水泥有限責任公司水泥生產的特點，以數據倉庫技術如何應用於銷售決策支持系統為例，提出了一個基於數據倉庫技術的決策支持系統的解決方案，著重論述了數據倉庫系統的設計方法和步驟，探討了如何通過聯機分析處理和數據挖掘技術實現數據倉庫系統的數據分析，論證了在浩良河水泥有限責任公司管理信息系統中建立基於數據倉庫技術的決策支持系統的必要性和可行性。Proceeding from the theory of region sustainable development and dss at first, the function and frame of regional sustainable development decision supported system have been analyzed ; then the oriented - object methods have been used to analyze the model base of the rsddss and set up the mbms which is fit for the rsddss ; on the above foundation, the issue of model intelligent selecting have been proposed, and the rational policy and methods to problem have been put forward on the basis of application of the intelligent technology such as nature language understanding, neural net etc. at last, the population forecast in the sustainable development decision supported system of hebei province has been taken as an example, to be carried on the positive demonstration research on the selecting of intelligent model
本文首先從區域可持續發展、決策支持系統的理論出發，對區域可持續發展決策支持系統（ rsddss ）的功能和框架進行了分析；然後運用面向對象的方法對rsddss的模型庫進行了設計，建立於適合於rsddss的模型庫系統；在此基礎上研究了模型的智能選擇問題，應用自然語言理解、神經網路等人工智慧技術提出了模型智能選擇相關的策略和方法；最後以河北省可持續發展決策支持系統中人口子系統的人口預測為例，對上述理論方法進行了實證分析。本文的研究對于rsddss的建立是一種有意義的嘗試，對可持續發展決策支持理論研究和實踐必將起到積極的作用。Intelligent decision support system for the stepped exploitation in the medium - and upper - reaches of shitou river valley bases on the basic theoretical frame and content as stated above, practice of intelligent decision support system in the stepped exploitation is explored by citing and analyzing a concrete instance of the stepped exploitation in the medium - and upper - reaches of shitou river valley, reflecting the feasible application of the view and theory put forward in this thesis in the practical planning
