概述了山地综合区划的原则和方法及图文信息可视化系统的涵义、结构、功能和建立路径。以湖南省怀化市为例 ,依托图文信息可视化系统 (MFIVS)技术手段 ,对山区综合区划进行具体尝试 ,得到的区划结果比较客观准确 。
Comprehensive division of the mountainous area, in allusion to the characteristics of abundant resources and frail ecosystemin the mountain area, make it in both accord with rationality of eco_environment and favor of development of society and economy. In object county or city order, Map and file information visibility system may make information mapificative and data visible by utilizing computer,GIS and database etc. technique. Taking the mountainous area Huaihua City as an example, being guided by regional difference law and mountain system theory, and on basis of the principles comprising of relative consistency (of ecological environment and territorial resources, social_economic, and regional comprehensive development direction,i.e .comprehensive valuation of PRED system), limiattion period, integrating area macrostructure with regional types and regionalconjugation, the paper adopts two bottom_up and tpo_down contrivance approaches, relies on the advanced measure_map and file information visibility system(MFIVS) etc., selects appropriate index system, and carries through integrate evaluation and clustering division. Comprehensive division of bottom_up approach adopts quantitative index_comprehensive evaluation index system. That is to say, in the light of the principles including integrating resources_environment with social_economy, combining spatial span with temporal limitation,uniting systematicness with dynamicness, linking integration with concision and holding relative integrity of district division to design index system(five grades and 52 single factors ),introduce the method of integrating ameliorated 3_grade IAHP and experientially estimating means to confirm the weights of various grades indexes,impose undimensionification_model of single index data_effect function to compute values of single indexes and composite indexes.According to these, it is taken that three comprehensive evaluations include system clustering analysis, gray constellation clustering analysis and fuzzy integrate analysis.Various appraise results mutually validate, and their results are approximately consistent. For various matter, e.g. weight values of indexes and insufficient source material etc.,however, there exists certain difference. From different maps drawn by utilizing Excel etc. software, two grades and three sub_kinds may be divided into. Otherwise, comprehensive division of top_down approach introduces synthetic qualitative indexes. Hereon, latitude location and traffic situation are meanly selected as consult indication of division. Synthesizing the results of two bottom_up and top_down approaches including four kinds of methods, Huaihua City is synthetically divided into two grades comprising of two regions and three sub_regions. Their names are A central low_hill, mounds and basin integrate economical region,BⅠ southern 1ow_mountain and mid_mountain forest_herd_tour integrate economical region, and B Ⅱ northern 1ow_hill and 1ow_mid_mountain forest_herd_mine integrate economical region, respectively.Finally, essential bases are put forward for the strategic thought of developing regional trait economy.
