( c ) land natural productivity increase from 7843 kg / ( hm2 - a ) to 17335 kg / ( hm2 - a ) relate to altitude closely , and the mean rate of enhancing yield is 23 . 53 percent in this region with annual enhancing - rate of 0 . 64 percent in last 15 years . ( d ) there are many facters that have been influe ncing soil effective coefficient that ' s soil organic matter , total nitrogen , effective phosphine and soil texture in turn . in a word , attenuation cause of land productivity is the result of water and soil . ( e ) the forestland potential productivity change from 3986 kg / hm2 to 15034 kg / hm2 , but it has a high distinction between southern aera and north area in yaan city . ( f ) the grassland potential productivity increase from 4085 kg / ( hm2 - a ) to 16973 kg / ( hm2 - a ) , but it has a high classification of potential productivity , ( g ) ditribution map was formed of potential land productivity . ( h ) it could be act as decision support for agriculture development , national land planning and ecotop constructive , etc 5 、土地自然生產潛力水平的主要土壤限制因素為有機質、全氮,其次為速效磷和土壤質地;區域潛在生產力差異的制約因素,主要為土壤,次為水分,水、土兩項衰減合計為45 . 99 ,石棉、漢源兩縣水、土衰減達到60左右。 6 、林地潛力在3986 15034kg / hm ~ 2之間,高等級林地比重小,以大相嶺為界,北部的各縣林地生產力水平高,南部的兩縣林地生產力水平較低。 7 、天然草地生產潛力水平高,潛力在16973 4085kg / ( hm ~ 2 ? a )之間,以高產的一、二、三級草地為主,且近10年來該比例變化不大。 |
