摘要 家庭花园在生物多样性方面是一个重要的考虑因素，但其重要性往往未被认识到。这项研究比较了两种不同生态环境下的家庭花园，以评估作物物种多样性。通过对两个不同生态区的家庭花园进行问卷调查和考察的方式进行评价；山区卡明保护区和巴维丘陵平原地区。结果表明，家庭菜园的物种多样性不理想：在总共观察的192个家庭菜园中，平均物种丰富度最高的是丘陵-平原生态区的一个村庄（12.84），最低的是卡明山区的一个村庄（1.71）。山区村庄生态欠发达。在蔬菜和夏季作物的划分方面，这三个预定义的类别（划分）都没有表现出任何特定的趋势，并且村庄之间几乎没有差异。但在果树和灌木的划分上，丘陵平原生态村庄的多样性明显较高，这种划分是家庭花园的第一组成部分，而在山地生态地区则不太显着（丘陵平原所有村庄的香农-韦纳多样性指数均达到1.5，而山地生态村庄的香农-韦纳多样性指数均小于1）。其他家庭园艺作物的划分表明，总物种丰富度较低，特别是山区生态，香农-韦纳指数清查显示，其中一个村庄得分最高，为0.73，涉及51科97种作物。卡明山区生态区仅发现33种农作物，Sorenson相似度指数评价表明，两个生态区生态相似度较低，得分为0.49
ABSTRACT Homegardens are an important consideration in terms of biodiversity and yet their significance is often unrecognized. This study compared home gardens in two different ecologies to evaluate crop species diversity. Evaluations were made by questionnaires and inspections of home gardens in two different ecological areas; the mountainous Khamin protected area and the Bavi hilly-plain area. Results showed unsatisfactory species diversity in home gardens: from a total of 192 observed home gardens, the highest mean species richness (12.84) was in a village on the hilly - plains ecological area and the least (1.71) was in a village in the mountainous Khamin area. Villages in the mountainous ecology were less developed. None of the three predefined categories (divisions) demonstrated any specific trend, in the division of vegetable and summer crops and there was little difference between the villages. However in the division of fruit trees and shrubs, villages in the hilly-plain ecology showed significantly more diversity and this division was the first component of home gardens, however, it was less remarkable in the mountainous ecological area (Shannon – Weiner diversity index for this group was up to 1.5 in all villages on the hilly-plain compared to an evaluation of less than 1 in all villages in the mountainous ecology). The division of other homegarden crops showed that total species richness was low especially in the mountainous area ecology and inventories on the Shannon – Weiner index showed the maximum score of 0.73 from one of the villages as 97 crop species relating to 51 families. Only 33 crop species were found in the mountainous Khamin ecology and evaluation by the Sorenson similarity index indicated low ecological similarities between the two ecological areas with the score of 0.49
