由於經濟快速發展，使得部份產業活動往山坡地移動，及部份開發改變地形、地貌及破壞水文及自然環境，相對坡地災害等威脅與日俱增，因此水土保持之重要性與日俱增。根據「水土保持法」第12條規定：『水土保持義務人於山坡地或森林區內從事下列行為，應先擬具水土保持計畫，送請主管機關核定，如屬依法應進行環境影響評估者，並應檢附環境影響評估審查結果一併送核。』。說明在山坡地或森林內特定情況下開發、整地等行為，須擬具水土保持計畫書及此計畫書可委託相關機關或團體審查。
水土保持計畫審查之目的在於透過事前審查機制，並結合專業技師之設計理念及經驗，促進土地合理利用及開發之安全。依照水土保持法各相關條文之規定，各式之山坡地開發與維護行為，需先擬具水土保持計畫，送請主管機關核定後方可進行施作。除雜項執照的管制部分須符合建管法令之相關規範之外，水土保持法規之部分，對工程監督與管理，主要依據為水土保持計畫審核監督辦法，此辦法中明列有各式表格資料、與施工監督、完工申報等各式流程架構與項目綱要，主管機關據以監督查核工程之進度與品質。
為達成永續發展應落實設施維護管理機制，因此本研究將對桃園市現行的維護管理機制進行統計並分析。

The importance of soil and water conservation is growing due to the rapid economic development, which makes some industrial activities move to slopes, and some of them develop terrain and topography, destroy hydrology and the natural environment, and increase the relative threat of sloping land disasters. According to Article 12 of the Soil and Water Conservation Law, "The following acts shall be carried out by the obligor of soil and water conservation on the hillside or in the forest area. The soil and water conservation plan shall be prepared and submitted to the competent authority for approval. In the case of environmental impact assessment , And should be submitted to the environmental impact assessment review results sent to the nuclear. ". Explain that in the case of hillside or forest specific development, land preparation and other acts, must be prepared with a soil and water conservation plan and this plan can be entrusted to the relevant authorities or groups to review.
The purpose of the review is to promote the rational use of land and the safety of development through the ex-ante review mechanism and the design concept and experience of professional technicians. In accordance with the provisions of the relevant provisions of soil and water conservation, all kinds of hillside development and maintenance activities, to be prepared with soil and water conservation plan, submitted to the competent authority for approval before the operation. In addition to miscellaneous license control part must comply with the relevant provisions of the Construction and Management Act, soil and water conservation laws and regulations of the part of the project supervision and management, the main basis for soil and water conservation plan audit supervision, , With the construction supervision, completion of the declaration and other types of process framework and project outline, the competent authorities to monitor the progress of the project and quality inspection.
In order to achieve the sustainable development, we should implement the facilities maintenance and management mechanism, so this study will analyze and analyze the current maintenance management mechanism of Taoyuan City.
