    摘要:

    城鎮(zhèn)土地利用規(guī)劃是城鎮(zhèn)化健康有序推進的基礎(chǔ),規(guī)劃實施監(jiān)測是其實施的保障。遙感和GIS相結(jié)合的方法可快速監(jiān)測城鎮(zhèn)土地利用規(guī)劃實施情況,保障土地利用規(guī)劃實施的動態(tài)管理。利用0.5m分辨率的WorldView 2衛(wèi)星遙感影像,采用面向?qū)ο蟮挠跋穹治龇椒?,針對基于知識規(guī)則分類特征選取及閾值確定難點,將CART決策樹與面向?qū)ο蠓诸惙椒ńY(jié)合,實現(xiàn)參與分類最優(yōu)對象特征的選擇以及特征閾值的自動確定。在分類基礎(chǔ)上,對每個規(guī)劃圖斑計算地類規(guī)劃實施完成率,實現(xiàn)對土地利用規(guī)劃實施過程進行監(jiān)測評價。最后,以北京市房山區(qū)某區(qū)域為研究區(qū),進行了試驗驗證。結(jié)果表明:最終分類總體精度達0.89,Kappa系數(shù)為0.87,表明構(gòu)建的分類算法基本能滿足城鎮(zhèn)土地利用規(guī)劃監(jiān)測的需求。研究區(qū)東北部土地利用規(guī)劃實施情況比西部好,公共綠地、水域等地類需重點調(diào)查監(jiān)測,同時二類居住用地的建筑密度偏高,綠化率偏低。

    Abstract:

    Urban-rural land use plan is the foundation of healthily and orderly sustainable development of urbanization and the monitoring of plan implementation is considered as the guarantee. The association of remote sensing and GIS is one of rapid and effective monitoring method for urban-rural land use plan implementation which strongly strengthens the dynamic management of land use plan implementation. We used high spatial resolution remote sensing imagery—WorldView2 with resolution of 0.5m and the objectoriented image analysis method to achieve the classification. The features and thresholds were determined with CART decision tree in objectoriented rule classification. On the basis of classification results, the completion rate of land plan for each plan patch was computed with the monitoring and evaluation of land use plan implementation. Finally, a subdistrict of Fangshan District,Beijing City was taken as the study area to illustrate the method. The results showed that the final overall accuracy of classification was 089 and Kappa coefficient was 0.87. The proposed classification algorithm can meet the basic needs of urbanrural land use plan monitoring. The implementation of land use plan in northeast study area is better than that in the west. The public green land and water area need to be investigated and monitored further as the key objects, at the same time, the density of second type residential building is a little high, while the green landrate is low.
