    摘要:

    選擇傳統(tǒng)的水體周長、水體總面積和河流密度以及最新的水體空間分布多樣性4類地表水體分布特征評(píng)價(jià)參數(shù),對(duì)河南省中部典型樣區(qū)的地表水體信息進(jìn)行深入分析。研究表明,當(dāng)研究區(qū)內(nèi)水體以河流等線狀水體類型為主時(shí),4者均能較好地描述區(qū)域地表水體的分布特征,且兩兩之間具有明顯的一元線性正相關(guān)關(guān)系,判定系數(shù)平均達(dá)到0.89左右;當(dāng)研究區(qū)由河流、湖泊、水庫等復(fù)雜水體類型構(gòu)成時(shí),選擇最新的水體空間分布多樣性評(píng)價(jià)參數(shù)能夠更好地描述區(qū)域地表水體的空間分布特征。

    Abstract:

    There is a significant spatial imbalance in the water resources distribution in China and the study on it is very important for the sustainable use of natural resources and rational distribution of agricultural structure. A typical research area in central Henan Province is selected for a correlative analysis about surface water distribution characteristic between the traditional indices (water perimeter, water area and drainage density) and the new water spatial distribution diversity methodology. Results show that there is a significant positive relationship among these four indices with the average coefficient of determination (R2) of 0.89 when the regional water is predominated by rivers or such linear surface water types, and in this situation each of these indices is suitable. However, when the regional water is predominated by rivers, lakes, reservoirs and such complex surface water types, the newest index ‘water spatial distribution diversity’ performs better and should be chosen in describing the water spatial distribution characteristic.
