watershed boundary 中文意思是什麼
watershed boundary
解釋
分水界-
Dem has abundant information about terrain, and we can extract the watershed basic characters, which include land surface characters, drainage network et al based on gis, and also can make certain the watershed boundary and set off sub watersheds from dem, which provide the flat roof for digital hydrological simulation
數字高程模型（ dem ）存儲了豐富的地形信息，通過gis可以提取流域的基本特徵，包括下墊面特徵、水系、河網等，並可以依據河網等級確定流域的邊界，進行子流域的劃分。為數字水文模擬提供了平臺。 -
In this paper, an algorithm based on watershed transformation and fuzzy logical catchment basins combination is proposed to suppress or remove the feature of natural background, and applied to infrared object boundary detection and labeling
文中在分水嶺演算法的基礎上，結合模糊邏輯方法，對自然背景下的紅外人工目標的邊界檢測和分割以及紅外背景的抑制進行了探討。 -
( 2 ) the construction of the digital watershed. this study extracted watershed drainage network, set off sub - watersheds and made certain watershed boundary. and this study also extracted some parameters about hydrology and terrain based on dem
在數字高程模型（ dem ）的基礎上，進行了流域河網的生成、子流域的劃分以及流域邊界的生成研究，並進行了與地形相關、具有水文學意義的部分參數的提取。 -
In the paper, the integrated research of characters, objectives, models, principles, index system and affecting factors of trans - boundary water resource allocatio is done : ( 1 ) the research progress in the trans - boundary water allocation in the past 10 years is summed up, and then the new development tendencies related are concluded ; ( 2 ) the key issues and difficulties on transboundary water allocation are judged through the analysis on the characters of trans - boundary water resource in both aspects of the natures and the international laws ; ( 3 ) the water allocation models as the whole allocation, the project allocation and the integrated watershed planning allocation are systematically analyzed ; ( 4 ) the technical index system is brought forward, their affecting items are discussed, and the major index are defined based on the analysis of allocation principles of the trans - boundary water ; and ( 5 ) the relative suggestions for the allocation of trans - boundary water resources in china are put forward
摘要綜合研究了跨境水資源分配的特點、目標、模式、原則、指標體系和影響等因素：對近10年來跨境水資源分配的研究進行了總結，歸納出新的發展趨勢；從自然和國際法兩方面屬性分析跨境水資源的特點，判識跨境水分配的核心問題和難點；系統地分析了全局分配、項目分配和流域整體規劃分配等分水模式；在分析跨境水資源的分配原則基礎上，提出了分水技術指標體系，並探討了其影響因數和主要指標的確定；結合這些研究，對我國的跨境水資源分配，提出了相關建議。
