解釋
有效高度-
With the development of science and tecbnology, the electronic warfare has gotten to a new stage, electronic jammers, anti - radialized missiles, superlow altitude attacks have turned into great threats confronted with radar nowadays. former single - based radar not only had difficulty in finishing expected tasks, but also the survival of itself had been a pressing problem, people have to probe into multifarious countermeasures in order to improve the viability and effective work - capacity
隨著科技的發展，雷達電子戰發展到一個新的階段，電子干擾、反輻射導彈、低空突防和隱身武器已成為當今雷達面臨的四大威脅。傳統的有源雷達不僅很難完成預定的任務，而且自身的生存也成了緊迫問題，人們不得不積極探討各種對策，以提高雷達的生存和有效工作能力。 -

( 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。 -
